That's what makes a report in the current Nature so promising. U.S. and European scientists have shown that patients can learn, by trial and error, to control a type of brain waves called slow cortical potentials. By hooking the patients up to a computer via an electroencephalogram, the researchers taught two ALS sufferers to mentally signal the computer to pick out letters on a screen, spelling out messages. The process is agonizingly slow--the average pace is about two characters a minute--but it should eventually improve. And compared with utter silence, it must seem blistering...
...WHOLE LOTTA SHAKIN' GOIN' ON Uh-oh, it's Jell-O. This year the gelatin dessert has its 100th birthday, and so in June its hometown of LeRoy, New York, opens an exhibit that will be part of a permanent museum. Trivia fact: an electroencephalogram shows that a human brain and a bowl of quivering lime Jell-O have the same waves...
...swift pace of biopsychiatric research has led to new tests for other mental illnesses. Leslie Prichep and her colleagues at the New York University Medical Center in Manhattan have retooled the electroencephalogram, or EEG, which measures the electrical activity of the brain, to identify various subtypes of schizophrenia, depression and other disorders. Their goal is to eliminate some of the trial and error that psychiatrists typically have to go through when prescribing pills for their patients. They have already seen results with obsessive-compulsive disorder, or OCD, a condition in which people continuously repeat the same sequence of thoughts...
They plan to go into schools in Boston and diagnose dyslexia in children as young as possible with a modified version of an electroencephalogram (EEG), which measures brain waves using electrodes attached to the head...
