Prefrontal Cortex and reinforcement

Question 1

Prefrontal cortex projects to

Answer 1

VTA and likely provides increased activation to VTA as actions are coming closer to achieving goals and presumably obtaining reinforcement

Question 2

Prefrontal not only provides input to

Answer 2

ventral tegmental area (VTA) to regulate dopamine, but also is a “target” of dopamine activation by way of NA->GP->thalamus->prefrontal cortex

Question 3

What is the pathway of prefrontal target of dopamine activation?

Answer 3

NA->GP->thalamus->prefrontal cortex
