Reward processing in the brain
Our group is interested to relate the mechanics of brain activity to measurable behaviour. We combine behavioural, neurophysiological and neuroimaging techniques to investigate the neural mechanisms of learning, goal-directed behaviour and economic decision making at the level of single neurons and individual brain structures. We use behavioural concepts from animal learning theory and economic utility theory to study the processing of reward information in specific brain regions, including the dopamine system, striatum, orbitofrontal cortex and amygdala. Further details are described in Scholarpedia (Reward and Reward signals). For more information on neuroeconomics see here.
