The effects of dopaminergic modulation on model-based reinforcement learning
- Abstract:
-
A functional polymorphism (Val158Met) in the catechol-O-methyltransferase (COMT) gene influences cortical dopamine and prefrontal cortex function in humans, both of which are important in learning and decision making. Moreover, dysfunction in the brain's dopamine circuits and mechanisms of decision making is observed during acute stress.
Mammals are thought to use two evaluation strategies in decision making, model-based and model-free reinforcement learning (RL), which have complem...
