Brown University's David Badre, an assistant professor of cognitive and linguistic sciences, and colleagues at the University of California"“Berkeley mapped parts of the brain that control abstract or concrete decision making by studying stroke patients. Their findings will be published March 1 in the journal Nature Neuroscience. A Brown University study of stroke victims has produced evidence that the frontal lobe of the human brain controls decision-making along a continuum from...
