Brain, liquefaction of

by Liam Heneghan

The following is an excerpt from my unpublished manuscript “A Shorter History of Bodily Fluids”

B.

Brain, liquefaction of: also known as encephalomalacia (from the Greek, μαλακία softening), necrencephalus (from Greek, νεκρο + κεϕαλή deadhead), ramollissement cérébral (from the French ramollissement cérébral), cerebromalacia (from the Greek, μαλακία a colloquial onanist, esp a vehicular onanist; cf blood, semen), cerebral softening (from the Old English soft meaning soft), or more commonly, softening of the brain (pronounced US /breɪn/). When the tissue affected is white matter it is called leukoencephalomalacia; polioencephalomalacia refers to necrosis of the gray matter. This condition may manifest as multiple Brainnecrotic fluid-filled cavities replacing healthy brain tissue. It is preferable to inspect this necrosis post-mortem especially if attempting to administer home remedies. If you are a sheep the following suite of symptoms will be diagnostically useful in identifying brain liquefaction: somnolence, short sightedness, ataxia (poor coordination), head pressing, tumblesaulting, walking in circles, walking bipedally, excessive bleating or bleating in prime numbers, and terminal coma. I treated a mouse once that after a fall complained to me that she could only walk in circles. It greatly affected her travel plans and she died penniless, vastly undereducated, and living very close to where she was born.

If after munching on yellow star thistle (Centaurea solstitialis) you become excessively sleepy or find yourself given to aimless wandering and go off your feed, you might be a horse. Unfortunately you also have a condition called nigropallidal encephalomalacia. Avoid prehending Russian Knapweed. If you are a chicken and have ataxia, paralysis, severe softening of the brain, and are brooding excessively on death you have “crazy chick disease”. Take vitamin E capsules with your feed and avoid gassy foodstuffs. Rhinoceroses should also remember to regularly get their vitamin E levels assessed; consider doing so even between regular checkups. If you are a Rhinoceros be vigilant for signs of depression; if you are feeling down, just pop in to your vet. If your condition has progressed to coma, its best to have him visit you.

Would you like people with that city?

by Misha Lepetic

The world has not been at any time different than it is now.

– ślokavārtika

Lewis Mumford, perhaps the 20th century’s most broad-ranging and eclectic thinker and critic concerned with the American urban experience, is remembered mostly as a messenger of modernism. Certainly, his open contempt of architectural ornament and of the City Beautiful movement in general was, like many of his counterparts, influenced by the dark and overwrought Victorian era that preceded it. However, modernism in general was enamored of the opportunities extended by new building materials and techniques – materials such as steel, glass and concrete that would be combined to create entirely new structures such as skyscrapers – which empowered it to leave behind the context of place. In contrast, Mumford’s concern was primarily humanistic, that is, one where an act of planning or design was primarily about the way in which the social life of a town, city or neighborhood could be understood, and only then improved.

Geddes Mumford was greatly influenced by Patrick Geddes, a peripatetic Scot whose diverse explorations lead him to apply Spencer’s idea of biological evolution to the investigation of society – that “society itself was an organism and that social progress was analogous to biological change” (Wojtowicz, p11). Mumford’s idea of the regional survey as the principal tool by which society, economy and nature could be holistically apprehended was derived directly from Geddes’s idiosyncratic, interdisciplinary style of thinking.

Along with Geddes, Mumford was also deeply influenced by Ebenezer Howard, who authored the Garden Cities movement, which was designed to combat inner city squalor by redesigning the urban concept into large towns of about 30,000 inhabitants, surrounded by an agricultural belt meant to make the city nearly self-sufficient (Howard was perhaps the last urban planner to take into account that people needed to eat as well as work, shop and sleep). These cities were meant to foster a deep and proximate connection to nature, and were intended to remain insular, their centers connected by light rail.

In all, not many of these designs were executed, and New Yorkers wondering how far away one ought to build a Garden City are encouraged to visit Forest Hills Gardens, which is now a part of Queens. Rather, the modernist enterprise took off with full force, and the holistic approach that Geddes and Mumford sought was buried in the succeeding tidal waves of boom, bust, war and post-war prosperity.

A Lament For Souza (In The Week Of Lucian Freud’s Death)

by Vivek Menezes

Not a single decade has passed, yet the circumstances of Francis Newton Souza’s last years already seem inconceivable. Souza Gallery One_jpeg

I’ve been stewing about this since coverage of the death of “Nudist painter Lucian Freud” inexplicably spread across the Indian press right into my morning papers here, a media backwater that is by far the smallest state in the country. But it was the same across the subcontinent – even the most obscure regional publications marshalled a deeply respectful send-off for the British painter.

Yet when Freud’s one time rival for the 1950’s London spotlight, the monumentally brilliant Indian painter Francis Newton Souza, died on 28 March, 2002 during a trip to Bombay, the news barely caused a ripple anywhere in the world.

He founded the Bombay Progressives in 1947 – unquestionably the single most important 20th century development for Indian art – but when he died in the same city more than 50 years later, Souza's body was consigned to shabby Sewri Cemetery, where only the unattached are sent to be buried. The old man had been near-indigent, selling his best work from the 1950's and 60's for two and three thousand dollars. Most of the stragglers graveside were art dealers, already jostling to feed from the artist’s corpus. It took no time at all for them to push his work to knock down million-dollar records at auction, but the shameful truth is that Souza burned livid right to the end of his life, shot through with pain about being abandoned, and totally ignored by the same trampling hordes of instant cognoscenti that now like to pretend they knew and acknowledged his worth all along. That's just a blatant, barefaced lie.

The Dignity of Skepticism

by Scott F. Aikin and Robert B. Talisse Empiricus

Being a responsible believer requires one to have reasons for one’s beliefs. In fact, it seems that having reasons for one’s beliefs is a requirement for seeing them as beliefs at all. Consider the conflict in thought that arises with assertions like the following:

I believe I live in Nebraska, but I have no idea why I believe that.

I hold firmly that there are jellybeans in that dish, but I have no reason for doing so.

I’m confident that it will not rain on the picnic, but I have no evidence for that.

I support a flat-tax system, but all of my information concerning economic matters is highly unreliable.

Statements like these are conflicted because in each the but-clause seems to retract the grounds for asserting what came before. To affirm, for example, that one lives in Nebraska is often to affirm also that that one has reasons that are sufficient to support that claim. Statements of the kind above, then, don’t look like they could be beliefs at all; they rather something else – perhaps a cognitive symptom, an obsession, a queer dogmatism.

We may say that beliefs are supposed to be not only reason-responsive, but reason-reflective. Our beliefs should be based on our evidence and proportioned to the force of our evidence. And so, when we hold beliefs, we take ourselves to be entitled to reason to and from them. So beliefs must be backed by reasons.

Reason-backing has a curious pattern, however. Each belief must be backed by reasons. But those backing reasons must themselves be backed by still further reasons. And so on. It seems, then, that every belief must be supported by a long chain of supporting reasons.

This is a point familiar to anyone who has spent time with children. Why? is a question that can be (and often is) asked indefinitely. The child’s game of incessantly asking why? may not be particularly serious, but it calls attention to the fact that, for every belief you hold, you ought to be able to say why you hold it.

These rough observations give rise to a deep problem, one that has been at the core of the philosophical sub-discipline of epistemology since its inception.

Mindfulness meditation: A primer and some thoughts

by Rishidev Chaudhuri

Laos-vipassana Among the meditative practices I’ve explored, Vipassana seems the one that is most easily seen as a principled way of exploring the structure of one’s experience and the one most easily separated from a religious or soteriological context. This is true even amongst the Buddhist meditations. For example, Zazen is fascinating but its goals seem different. It pays great attention to exactly how you should position your body but tells you little about what you should do with your mind. The idea seems to be that, since you are already enlightened, active exploration or instruction in mental technique is a hindrance, and you just need to recognize your inherent enlightenment. On the other end of the spectrum, the practices derived from the esoteric Buddhisms (like Shingon and the Tibetan schools) rely heavily on symbols and their unpacking. This is a simplistic classification and mindfulness meditation appears in the other Buddhist traditions (even if not as prominently), but it’s one that I think is roughly true.

The general principle in Vipassana is to train one’s attention through focus on a particular object and, once this is well-trained, to use it to observe the unfolding of experience. It’s effectively a systematic way of noticing experience. The breath is typically the chosen focus. As far as I can tell, this choice is semi-arbitrary but has a number of advantages. Apart from the comforting stamp of tradition, the breath is both ever-present but also changes with emotional and mental state, giving a good starting ground both for training concentration and for training mindfulness of the multiple aspects of one’s state.

So here’s a sketch of how you might start off:

Sit down (on a chair, on the floor, cross-legged or not, it doesn’t matter) and bring your attention to the edge of your nostrils, where your breath enters and leaves. Again, all you want is an anchor point that you can use to train your concentration and to return to when your mind starts to get swamped by thoughts. Other foci would work.

The Shape of Things To Come: Saatchi Gallery, London

by Sue Hubbard

Saatchi Gallery, London. Until 16 October, 2011

ScreenHunter_13 Jul. 25 10.37 What, I wonder, would a visitor from the future make of the sculpture show The Shape of Things to Come at the Saatchi Gallery if they were to visit it, say, in a couple of hundred years time? What would it tell them of the state of the society that had made this artwork? Seen from such a distance those coming back from the future might be forgiven for thinking that this was an era of extreme distress, one that lacked confidence, dreams, vision and hope. Smashed cars wrapped around pillars, sexual orgies of faceless participants, horses in a state of destitution and collapse, and fragments everywhere speak of a community that has lost faith in itself and the future. Compared to the thrusting optimism of Modernism with its utopian faith in the benefits of technology and scientific progress, the world presented here is one of post-technological ruin, distortion and despair.

Previous shows put on by Saatchi have been packed full of irony, a cheeky in-your- face insouciance that when it first arrived in the brazen 80s and 90s was iconoclastic, witty and fun. But over the passing decades it has all too often become the default position of many young artists eager to make their mark. Form has dominated over content, while meaning and metaphor have often been subsumed to novelty for its own sake.

In contrast this show, rather ominously, opens with a gallery full of megalithic boulders. Kris Martin’s found stone slabs look like pre-historic monoliths from some lost pagan religion. Each is topped with a fragile, almost invisible paper cross. In its monumentality the piece is reminiscent of Joseph Beuys’s The End of the Twentieth Century. Its meaning is fluid. Man’s success in conquering the limits of awesome nature, the ruins of war and the collapse of civilisations are all implied. The tiny crosses equally suggest the shrinkage of faith in a late capitalist age or, depending on your point of view, act as tiny beacons of hope. “Dreams are what keep people going.” Martin says.

How to Write about Congo

Book Review: Dancing in the Glory of Monsters. The Collapse of Congo and the Great War of Africa, Jason K. Stearns (Public Affairs: 380pp, 2011)

byDancing-in-the-Glory-of-Monsters-Stearns-Jason-9781586489298-1 Edward B. Rackley

How best to make sense of Congo’s enduring crisis, a tale of daunting political complexity and extraordinary cruelty? Many writers have tried, for no other African country captivates the western literary imagination as much as Congo. This fascination long precedes Joseph Conrad, who indelibly described King Leopold’s Congo Free State over a century ago. But faithful subjects do not good art make, and most western writing on Congo is unreadable or, at best, unbearable.

The sheer complexity of Congo’s dramatic history is one contributing factor behind all the dreadful writing. Many an author sacrifices compelling narrative for rigorous scholarship, resulting in a turgid swamp of acronyms for all the armed groups, the Security Council Resolutions and the doomed peace deals. Epic chronicles like Africa’s World War (Gérard Prunier) may be valuable to scholars but are so microscopically detailed as to be opaque to non-specialists.

Adventure writing, the other main genre of Congo literature, is equally abundant and can carry a plot, but the stories glorify the exploits of the author and ignore the Congolese. “Watch me as I commune with gentle pygmies, wrestle crocodiles on the great Congo River, escape beheading by a throng of stoned child soldiers”— setting the bar for unbearable reading. Common to both schools is the absence of Congolese voice; for both, Congo is a neutral, muted stage for the author’s performance (scholarship, “survival”). Faced with such output, one thinks, the trampling of Congo just goes on and on.

Safe Words

by Justin E. H. Smith

Lfm71 The first thing you need to understand about the BDSM community is that we are committed to one thing above all: mutual respect. We respect each other's kinks, and we seek to help one another to realize our fantasies.

Some people have fantasies of being dominated, and those of us who help them to realize these fantasies are not in the end looking to hurt them, or to abuse them, but only to help them. It might look cruel from the outside, but in the end it's all about respect (and mutual pleasure!).

Some in the community even affirm their commitment to mutual respect by taking a solemn vow. This is what my partner and I did early in our relationship (going strong since 2002). I said, “Laurence, I hereby swear to respect the integrity of your person, to respect your will, and your inherent right to realize your fantasies, and I promise to help you to realize them without harming or abusing you.” And he said, “Russell,” and then went on to recite the same little speech.

A central part of this commitment to mutual respect is the choice of what are called 'safe words': when the domination becomes too severe, when the fantasy pleasure begins to cross over into real displeasure, the submissive is able to call a halt to the session by exclaiming a word that has been agreed upon in advance, such as usufruct or plutonium, which signals that he has had enough, that the fun is over and he needs to be released.

For a long time this arrangement worked very well for us. I would have him gagged and bound, joyfully raising welts on his buttocks with a bushel of birch twigs, when suddenlly he would mutter through the bandana in his mouth: baleen! Some other day it would be corn pone, or carpetbagger, or drumlin, or orange roughie, but the message always came through loud and clear: Laurence couldn't take it anymore. Laurence had had enough. Cease and desist, Russell. It's about respect.

The hallucinogenic meaning of mantras

by Hartosh Singh Bal

Harappa For a tradition that seems to extend back to the Harappan civilization, our lack of knowledge of some key aspects of Indic religions continues to be baffling. One problem, of course is our inability to unlock the world of the Harappans. Signage and seals are available in large number but so far progress in deciphering them has been slow. Over the past few years an acrimonious debate has been underway between those who claim that we can bring new tools to the job such as Rajesh Rao and those such as Steve Farmer who argue that the script is actually no more than signage and is not in fact a writing system.

This argument over the meaning that can be ascribed to signage is reminiscent of another area of Indic studies, which while not mysterious in the same way, remains baffling to me – the meaning of mantras.

The word mantra has entered the English language as a ritual chant, a magic formula repeated over and over. As a definition this only partially conveys the sense in which a large number of Indians even today understand the word. Perhaps, in no other part of the world does a non-tribal tradition lay so much stress on the power of particular Sanskrit words chanted in a particular order to harm or heal. The mantra is at the heart of most tradition of Gurus and disciple where the initiation is connected to the passing on of a guru-mantra tailored to the individual disciple, often unique to him. This is a tradition that extends to closely related religious forms, such as Tibetan Buddhism, which also lay great stress on mantras. This is as far as healing goes, the ability to harm is also explicitly identified with the term. In popular usage the entire phenomenon of spells, witchcraft etc are often subsumed under the practice of tantra-mantra.

Interesting though this may be from the sociological or anthropological point of view, I am more concerned by what a skeptic or a rationalist is to make of this. One possibility is to ignore this as so much mumbo-jumbo (or tantra-mantra) but to me that makes little sense when faced with a tradition that relies so much on experiential knowledge as a basis for belief. What possible experience could explain the origins of this belief in the power of mantras?

The Legend of Marcus Aurelius

by Jenny White

LegendBerlinPhotobyJennyWhite

My friend and colleague Corky White likes to regale me with family legends, some of which are quite dramatic in both human and historic terms. They form a stark contrast to my own family history, much of which is unknown, and the part that is known consists of Bavarian peasants all the way down. At some point my grandparents moved from the Old Mill Valley to a regional city and their offspring spread themselves wide across the class spectrum and, in our case, across the globe. My uncle once put together a shallow genealogy, showing where family members were born, toiled, reproduced, and died. There are personal sagas involved in all this – my grandmother met my grandfather when they worked on the same farm, she as housemaid, he as stable boy. He stole up the stairs at night. My mother brought me with her on an ocean liner that docked in New York, where neither of us had ever been. But these are not family legends, they are not even stories people tell each other. They’re too personal, or too uninteresting to other family members who, after all, are living their own complicated stories.

What’s the difference between people who trace genealogies and families like Corky’s that collect legends? As legend has it, Corky’s grandfather, Mark Isaacs, was Abel to his elder brother’s Cain. Cain was Sir Rufus Isaacs, Marquess of Reading, Viceroy to India, who was implicated in the 1912 Marconi scandal in England. Somehow Sir Rufus put the family shame on Mark, who was expunged from the family and given a choice of Canada or Australia, where criminals were sent. If you google Marconi Scandal, you find a third Isaacs brother mentioned who actually managed the Marconi Company, but not the youngest brother, Mark aka Abel. Corky’s legend diverges from the historical narrative because legends privilege those parts of the story that have psychological saliency for the group that owns the legends. What do people learn or gain from performing these narratives at the dinner table, in the car, to children and friends?

Why Do We Read Detective Stories?

by Mara Jebsen
Sexy_target02 All men must escape at times from the deadly rhythm of their private thoughts. —Raymond Chandler

Last month I was a tourist for the first time in my life. I went to Athens and two islands in the Aegean sea. On the tiny island of AntiParos I felt a curious emptiness I associated with the matte heat of the blue air, and if I had a thought, it was that I could not think.

But you can’t stare at the sea endlessly. So I did what lots and lots of people do—I read detective novels.

And yesterday I devoured yet another Agatha Christie. And Saturday I watched the entire Bourne Trilogy in a sitting. At first I thought I was just maintaining the dusty mindlessness of my vacation. But no. The thing is I don’t know why I love detective novels, spy novels, thrillers–and I’m trying to get to the bottom of it.

And so, a little sleuthing. It turns out lots of wildly clever people have taken a stab at understanding the draw of the mystery, the thriller. But the results are disheartening.

Just last summer Joan Accocela did a piece in the New Yorker on Agatha Christie. It was sort of a bio piece, but the verdict on whether or not Christie was a ‘real artist’ (most of the time) seemed clear. It’s revealed that Christie herself understood her characters as little chess-pieces to be moved about committing murder willy-nilly. Acocella’s article implies that the pleasure we get from a suspense novel has more in common with the joy of completing a crossword than it has to do with art, or literature. And according to the biographical sketch, Christie is no help in this. I’m a poet, and as a supposedly ‘literary’ person who feels mildly guilty reading formulaic mysteries, my guilt is totally confirmed when I learn that the author felt guilty about writing them.

But what is going on here? Why would Christie and I repeatedly submit to this exchange of guilt- feelings, each sure that we are somehow superior to the shameful activity we’re engaged in?

Sunday Morning in a Northeastern Old Growth Forest


by Wayne Ferrier

God is the experience of looking at a tree and saying, “Ah!”

–Joseph Campbell

Old Growth Canopy Mohowk Mahican Trail Mass Most people, who reside in the Northeastern United States, don’t know that there are remains of old growth forests scattered here and there among them. And most don’t care. The human species is not hard-wired to appreciate these things. The people who do appreciate them have a difficult time digesting this, but it’s true. Most people’s world view is a social reality imprinted and reinforced by the way other human beings look at the world. Human beings are social animals and few could survive alone in the wilderness; they’d starve or succumb to the elements. However, most would lose their sanity long before the unforgiving laws of nature would get them. We see this phenomenon in our prisons, where inmates prefer to be out in the yard even if “out in the yard” there are other inmates waiting there to kill them. Being killed by one’s fellows is far more preferable than the worst of fates—solitary confinement. In ancient times the worst thing that could happen to you was banishment.

Moral Cement

by Jonathan Halvorson

It’s a rusty but sturdy old truism to say that morality binds societies together. As shared outlooks for moral praise and blame dissolve, a society enjoys more the mixed blessings of contention from fragmented sub-groups with divergent political goals and manners of living. The “culture wars” in America and other nations provide easy examples of the dynamic in action.

A flotilla of social sciences have by now devoted literally millions of hours to understanding how these social disagreements arise, explaining how they persist, and providing models of how the differences in belief about what is good can drive differences in beliefs about facts. Shared morality doesn’t just get tied up with a shared outlook on what is good, but a shared outlook on what is.

And so the culture wars and other disagreements about morality (broadly construed) drive wars about the truth of global warming, whether homosexual households are harmful to children, whether deficit spending during a recession spurs economic growth, whether higher taxes on the wealthy hinder economic growth, whether social programs help the poor they are meant to serve, whether torture is a useful method for gathering intelligence, the health effects of pollutants, and on and on.

Your reaction is probably along the lines of: Yes, and what a shame. The facts are what they are whether or not we want to believe them. Truth is cold. We shouldn’t let our beliefs about good and bad influence in any deep way our beliefs about objective facts of the world, especially facts about the causes of things. But, in that same spirit of objectivity, the evidence is also clear: people hate cognitive dissonance and succumb to all kinds of irrational belief generation mechanisms to remove recalcitrant facts from their line of vision. When push comes to shove, it’s the facts that get revised to fit the normative commitments more often than we would like to admit.

Gods and Penises

by Fred Zackel

OsirisIsisHorus Does your god have a penis?

No, really. Yes, I am going somewhere with this train of thought. See, for example, if Jesus was married, then He had to use His penis, or He really wasn’t married, was He? Oh. You don’t like the image in your imagination. Geez, you got a naughty mind.

A question of morality, you say? If we think it’s disgusting, then we mean it’s immoral. A good working definition right out of Evolutionary Psychology for a world of relativism.

Think of Osiris. In one version, he got chopped piece by piece by his enemy Set, who scattered the god’s pieces everywhere on the planet. Isis, who was Osiris’s sister and wife, scrambled around on all fours and found all the pieces of Osiris, save one. You guessed it. Her spouse’s penis. Think about it: Isis, the goddess of fertility with an impotent husband. Sheesh. That is the very definition of irony, right?

(I have noticed the God of Irony always seems to trump the God of Justice. I always wondered: Was Oedipus alive just to entertain the gods?)

I bring up Isis because wives are linked to their husbands’ penises; she cannot be his wife if he has no penis, right? Well, conventional wisdom says.

Tell her the proper name of things
This is barbed wire
This is a watch-tower (so unlike the one in Brooklyn)
These are thermal imaging video cameras
These are 25-foot-high concrete slabs
Don’t tell her this is a fence
Tell her it is a wall

Teach her to spell a p a r t h e i d

Tell her about the 200 nukes in the Negev
Tell her how freedom-loving Yanks are aiding
History’s most persecuted minority
The specious democracy in the Middle East
The colonial-settler state embracing Biblical pretensions
To systematically exterminate
The world’s most dispossessed tribe

Tell her the truth so she grows up to speak its name

A Pakistani Let Loose

by Haider Shahbaz

“To be exiled is not to disappear but to shrink, to slowly or quickly get smaller and smaller until we reach our real height, the true height of the self.” – Roberto Bolano, Exiles.

“You must remember that there is nothing higher and stronger and more wholesome and good for life in the future than some good memory, especially a memory of childhood, of home.” – Fyodor Dostoyevsky, The Brothers Karamazov. Portrait-of-Gertrude-Stein-by-Pablo-Picasso

I packed my bags, and came to Paris. I am trying to write. What better place to write, I thought? After all: Hemingway, Stein, Cowley, Joyce, Fitzgerald. Also, my introduction to American fiction: James Baldwin. He came to Paris so as not to commit suicide, and to write. Preparing for my writing, I read ‘A Moveable Feast’ and reread ‘The Sun Also Rises’. I got drunk. I went to the graves of Abelard and Heloise and Sartre and Beauvoir. I accepted Baudelaire as a prophet and became a flaneur. I visited the Latin Quarter and tried to sniff out the ghost of a young Danny the Red. I read about Malte Laurids Brigge and I read the essays of Benjamin. I got high while I read Baudelaire and Benjamin. I even saw Midnight in Paris: It was cute.

But I didn’t write. I couldn’t write – no words, no stories, came to my mind. Unfortunately dear reader, the history of my travel and my failure to write neither begins nor ends at Paris. It begins, in fact, with my first love.

The Thirty-Third Internet Connection in New Delhi

by James McGirk

19modem110baudangle I never had a problem with Alaskan Senator Ted Steven’s oft-mocked remark about the Internet being a series of tubes. I saw it with my own eyes (metaphorically speaking) as a teenager growing up in New Delhi. The Internet was a feed of information that trickled in drip by drip, slowly increasing as we switched our faucets and eventually tapped into the municipal supply. My father was a foreign correspondent, which meant he had to send stories back home to be published. When we left “on assignment” to India he was issued with a bag of sophisticated telecommunications equipment. We plugged it in and became early adopters.

Our first modem looked like a cross between a swimming cap, a spider, and a rubber truncheon. There were two cups that stretched over the mouthpiece and receiver of a standard analogue telephone. One contained a microphone and the other a speaker. The modem would whistle and hiss signals into the phone, and listen for responses. It was a crude but robust system, the only thing capable of working on lines that were filled with crackling static and echoes, and may well have been tapped. Entire sentences would be garbled by line noise, or more insidiously the changes could be almost invisible. A pound sterling inserted where a dollar sign once stood.

Dad’s squealing octopus of a modem might have made things easier for everyone else, but it tossed a sabot into the gears of my imagination. Before we had left, he had taken me on a tour of his office and the printing press below. Communications made sense to me afterward. The newspaper was like a factory: an office space above filled with glowing amber terminals and stuttering typewriters and piles of important paper being fed to the machines below. The presses were magnificent, booming and huffing and spattering ink at rolling reams of paper. I could easily imagine the process as an unbroken chain extending across the world, see a pale English editor with a phone clenched between his shoulder and ear, transcribing dad’s story click by click into a typesetting machine to be turned to molten lead, slotted into a drum, dunked in ink and pressed onto fresh newsprint a hundred times a minute.

All things change; nothing is extinguished

by George Wilkinson

The Motion Aftereffect illusion, or Waterfall illusion, occurs when prolonged viewing of motion in one Choushi-waterfall direction makes a subsequently viewed stationary item appear to move in the opposite direction. An example is seen in this short video. The viewer fixates on a stationary blue point near a pattern moving toward the top of the screen. When the pattern is replaced with a fixed photograph of a waterfall, the water appears to flow toward the bottom. We see motion because our visual system adapted to the upward motion of the first stimulus, and that adaptation carries over for a few seconds affecting our perception of the stationary image.

This illusion is thought to reflect adaptation of neurons in the visual cortex responsible for detecting motion. In this model, overall motion perception results from a comparison of the relative firing patterns among neurons sensitive to diverse specific directions of motion. A stationary scene results in balanced outputs for all directions. In the classical Motion Aftereffect illusion, prolonged stimulation with one direction of motion leads to decreased output by the neurons sensitive to that direction of motion. When the stimulus is removed, output from that set of neurons remains lowered. But because the output from the other motion-sensitive neurons is higher by comparison, the resultant imbalance creates the perception of motion opposite to the original moving stimulus.

Althoug classical studies of the Motion Aftereffect illusion used a conditioning stimulus lasting several seconds, it is known that neuronal adaptation can occur much more quickly– on a timescale of milliseconds. Could perceptual adaptation be observed at brief timescales, relevant to the timescales in which neurons adapt? A recent study from the lab of Duje Tadin finds that the Motion aftereffect illusion can be observed even after very brief exposure to a moving stimulus. Subjects shown a video of a pattern that is moving for only 1/40 of a second (25 milliseconds) – so short that they can’t consciously distinguish its direction of motion – will then perceive motion in the opposite direction of the briefly presented background motion when viewing a stationary object. The implication of their results is that the cortical processes involved in the Motion Aftereffect illusion could affect our perception virtually every time we view motion. The work of this lab and others suggest that there may be more than one brain region, and more than one neuronal circuit, contributing to this class of illusion.

On FAMiLY Leader, Homosexuality, and Crippling the Institution of Marriage

by Tauriq Moosa

Michele-bachmann-817-cropped-proto-custom_2 I imagine that most of us are relieved to hear that Republican Michele Bachmann is going to become the first presidential candidate “to sign a pledge created by THE FAMiLY [sic] LEADER, an influential social-conservative group in Iowa.” Ms Bachmann, by signing the pledge, “vows” to “uphold the institution of marriage as only between one man and one woman.” The best is the Vow which calls for the banning of all forms of pornography. Oh and by the way, my gay and lesbian comrades, homosexuality is not only a choice but a “health risk”.

There are number of ways to look at this. Firstly, we can look at the political machinations involved, demonstrating what the human animal is willing to grab hold of in order to maintain the velocity of power as she swings from one constitutional branch to another. Or, we might consider the actual document itself that makes claims equally baffling and, to put it politely, arrogant.
