Document Summary
The ventral prefrontal (pfv) cortex consists of the orbital prefrontal (pfo) cortex and the ventromedial prefrontal (pfvm) cortex. The pfo is located at the ventral surface of the frontal lobe and covers the brain above the eye orbits: pfvm lies adjacent to pfo o. It occupies the medial extent of the ventral surface. The role of the ventral prefrontal cortex: the pfv has inhibitory connections with the amygdala which are responsible for suppressing emotional responses in social situations. Two were good decks and two were bad decks: selecting cards from the good decks lead to low rewards but low penalties, selecting cards from the bad decks lead to high rewards but high penalties. The iowa gambling task: choosing from the good deck leads to a net gain over the long run, choosing from the bad deck leads to major losses over the long run. They were also able to produce expressions that were recognizable.
