How drugs hijack decision-making in the brain


How drugs hijack decision-making in the brain.

A new cognitive science study by substance abuse researchers has discovered that an area of the brain called the orbitofrontal cortex is responsible for decisions made on the spur of the moment. However, this brain region is not responsible for decisions made based on prior experience or habit.

University of Maryland School of Medicine researchers report that experts had previously believed a single area of the brain was responsible for both types of behavior and decision-making.
