isability in decision making. Knowing which lesion leads to which outcome is something only this kind of detailed lesion study can provide, he says.

"That knowledge will be tremendously useful for prognosis after brain injury," says Adolphs. "Many people suffer injury to their frontal lobesfor instance, after a head injury during an automobile accidentbut the precise pattern of the damage will determine their eventual impairment."

According to Tranel, the team is already working on their next project, which will use lesion mapping to look at how damage to particular brain regions can impact mood and personality. " There are so many other aspects of human behavior, cognition, and emotion to investigate here, that we've barely begun to scratch the surface," he says.
