Brain maps reveal where decisions happen

Data studied over 30 years has revealed that reasoning and behavioural control depend on a different area from decision-making in the frontal lobe part of the brain.

Researchers mapped the brain activity of patients with frontal lobe damage, enabling them to see exactly which parts of the frontal lobes are critical for tasks such as behavioral control and decision making.

“The patterns of lesions that impair specific tasks showed a very clear separation between those regions of the frontal lobes necessary for controlling behavior, and those necessary for how we give value to choices and how we make decisions,” said a researcher from the team.

This knowledge will be helpful for prognosis after a brain injury.
