It was announced last week that scientists have integrated neurons from human brains into infant rat brains, resulting in new insights about how our brain cells grow and connect, and some hope of a deeper understanding of neural disorders. Full story here. And while no scientist would admit they are working toward the development of some Rat Man who will escape the lab and wreak havoc on some faraway island or in the subways, it’s impossible not to wonder.
There are some legitimate and difficult ethical questions in this territory, such as whether we should work toward “curing” all conditions labeled as “disorders”, including those conditions that have become woven into people’s lives so thoroughly that they would rather not lose them. Autism, for example, can be a terrible burden in some cases, but in others it serves as a valued feature of one’s individuality, an element in the core of who they are. It’s difficult to follow the precept of doing no harm as we dig deeper into human natures and find it’s not always obvious what counts as a harm. There is a medical/pharmaceutical mindset that likes to pound down any nail sticking up, which is running into the fact that some nails prefer to stick up, thank you very much.
But as we leave those problems to more insightful minds, I would like to turn instead to an illegitimate and silly worry, which we shall call “Ewww”:
Ewww = What if my neurons end up in a rat brain? Would I feel its whiskers twitching, feel hungry for garbage, and find fulfillment by running endlessly inside a little wheel?
As I said, it’s not a legitimate worry, but it’s hard for many of us not to feel a tug in its direction, because many of us are entranced by illusions about consciousness. Read more »
