"Haldeman, Joe - None So Blind" - читать интересную книгу автора (Haldeman Joe)cholecystokinin, for the same reason that Cletus learned how to play the violin.
Their love grew and mellowed, and at the age of 19, between his first doctorate and his M.D., Cletus paused long enough for them to be married and have a whirlwind honeymoon in Paris, where Cletus divided his time between the musky charms of his beloved and the sterile cubicles of Institute Marey, learning how squids learn things, which was by serotonin pushing adenylate cyclase to catalyze the synthesis of cyclic adenosine monophosphate in just the right place, but that's actually the main part of the story, which we have been trying to ignore, because it gets pretty gruesome. They returned to New York, where Cletus spent eight years becoming a pretty good neurosurgeon. In his spare time he tucked away a doctorate in electrical engineering. Things began to converge. At the age of thirteen, Cletus had noted that the brain used more cells collecting, handling, and storing visual images than it used for all the other senses combined. "Why aren't all blind people geniuses?" was just a specific case of the broader assertion, "The brain doesn't know how to make use of what it's got." His investigations over the next fourteen years were more subtle and complex than that initial question and statement, but he did wind up coming right back around to them. Because the key to the whole thing was the visual cortex. When a baritone saxophone player has to transpose sheet music from cello, he (few women are drawn to the instrument) merely pretends that the music is written in treble clef rather than bass, eyeballs it up an octave, and then plays without the octave key pressed down. It's so simple a child could do it, if a child wanted to play such a huge, ungainly instrument. As his eye dances one-to-one transformation that is the theoretical equivalent of adding and subtracting octaves, fifths, and thirds, but all of the actual mental work is done when he looks up in the top right corner of the first page and says, "Aw hell. Cello again." Cello parts aren't that interesting to saxophonists. But the eye is the key, and the visual cortex is the lock. When blind Amy "sight-reads" for the violin, she has to stop playing and feel the Braille notes with her left hand. (Years of keeping the instrument in place while she does this has made her neck muscles so strong that she can crack a walnut between her chin and shoulder.) The visual cortex is not involved, of course; she "hears" the mute notes of a phrase with her fingertips, temporarily memorizing them, and then plays them over and over until she can add that phrase to the rest of the piece. Like most blind musicians, Amy had a very good "ear"; it actually took her less time to memorize music by listening to it repeatedly, rather than reading, even with fairly complex pieces. (She used Braille nevertheless for serious work, so she could isolate the composer's intent from the performer's or conductor's phrasing decisions.) She didn't really miss being able to sight-read in a conventional way. She wasn't even sure what it would be like, since she had never seen sheet music before she lost her sight, and in fact had only a vague idea of what a printed page of writing looked like. So when her father came to her in her 33rd year and offered to buy her the chance of a limited gift of sight, she didn't immediately jump at it. It was expensive and risky and grossly deforming: implanting miniaturized video cameras |
