...Vilayanur Ramachandran and Edward Hubbard of the University of California at San Diego. Their studies take advantage of a perceptual quirk: when an image in the periphery of our visual field is surrounded by similarly shaped and colored images, the brain has trouble registering its presence--even though the eye picks it up. They reported at a meeting of the Vision Sciences Society in Sarasota, Fla., last week that even when synesthetes can't "see" a peripheral image--say a 5 that's "crowded" by 3s--they see the color associated with the digit in question. That suggests that synesthesia...
After an academic career that took him from the Himalayas to Harvard, Business School professor Ramachandran Jaikumar died last week of a heart attack while mountain climbing in Ecuador...
Since I'm sure that's what the editors want to do anyway, I hope you'll start making steps to correct this policy of using "gay" as a toned down code word for "queer." It is wrong factually, as well as limiting, backwards and reductive. --Gowri Ramachandran, GSAS...
Indeed, the brain abhors a vacuum, observes neuroscientist Dr. Vilayanur Ramachandran of the University of California at San Diego; it craves information, and when it can't come by the data honestly, it does the best it can with what it has. One of his patients, for instance, a physical-therapy professor from San Antonio, Texas, suffered a brain hemorrhage that left a huge blank spot in her otherwise normal field of vision-or, rather, it would be blank if her brain allowed it. First, she saw a drawing of a cat, presumably supplied by her visual memory. "Then," says...
Even when a limb is gone, its place on the mental map remains, and the neurons formerly responsible for processing sensations from it occasionally fire at random-the sensory equivalent of Mickey Mouse hallucinations. The brain also attempts to make up for the deficit physically, perhaps, suggests Ramachandran, by sprouting new sets of connections. Because neurons that process information from the arm are near those that handle the face, for example, these new connections can cause a blindfolded patient to think a gentle touch on the face is really a touch on a missing fingertip. Says Ramachandran: "Reorganization can occur...
