Scientists Tease the Brain to Give Up its Secrets
November 13, 2003
The modern metaphor for the brain is a computer, but that hardly begins to capture how extraordinary the human brain is. Just take one example—what Martha Farah, professor of psychology and director of the Center for Cognitive Neuroscience calls “knowledge systems.”
“ I could ask you what you know about, for example fire regulations, to pick an obscure topic,” explained Farah, “and you would be able to tell me something. How is that knowledge represented in your brain? How is it so accessible? This is the holy grail of artificial intelligence, but we do it easily, all the time.”
