\"\"Our brain<\/a> may be a hybrid of two ancient nervous systems that were packaged together hundreds of millions of years ago. This is based on the finding that the front and back brain regions in people and several other species develop from two distinct cell types in embryos, instead of sharing the same developmental origin, as previously thought.<\/p>\n

\u201cOur research suggests that evolution took two existing neural systems and pushed them together spatially,\u201d says Kyle Loh<\/a> at Stanford University in California. \u201cHaving the brain as one organ would probably be more efficient, but we rely on this primordial way to make the brain as two separate pieces.\u201d<\/p>\n

This is true even when you think someone else plays certain pieces of music better than Gould does. If I could listen to only one pianist play Bach, it would be Murray Perahia, not Gould. But when I first heard Perahia\u2019s Bach, I had been listening to Gould\u2019s Bach for a quarter of a century, so that for every minute in which I am lost in Perahia\u2019s playing, there is a second in which I think,\u00a0Hmmm, Gould wouldn\u2019t have played it that way.<\/em><\/span>\u00a0And even when I say that to praise Perahia, which is usually the case, Gould remains the benchmark for my judgments. This is equally true when I listen to Andr\u00e1s Schiff or Jeremy Denk.<\/p>\n
