Reward processing in the human brain. Insights from fMRI

摘要: Publisher Summary Reward processing engages diverse brain regions, including multiple prefrontal regions and the basal ganglia (particularly multifaceted striatum). Corticostriatal circuits are involved in computation of subjective value for experienced rewards, leading to a valuation signal that can be used guide future decisions via reinforcement-learning mechanisms. In recent years, an explosion neuroimaging research has replicated extended findings from rich body animal literature on basic reward systems probe how such modulated by more complex processes typically influence goal-directed behavior human society. The goal this chapter is discuss integration studies processing, with emphasis cortical-striatal reward-related information. Neuroimaging highlights functional subdivisions within components corticostriatal circuitry. number additional factors, magnitude reward, risk, time, social context. Furthermore, signals presence factors as Important directions include study modulation well aversive information also modulate behavior.
