Neural systems implicated in delayed and probabilistic reinforcement

@article{citeulike:882526, abstract = {This review considers the theoretical problems facing agents that must learn and choose on the basis of reward or reinforcement that is uncertain or delayed, in implicit or procedural (stimulus-response) representational systems and in explicit or declarative (action-outcome-value) representational systems. Individual differences in sensitivity to delays and uncertainty may contribute to impulsivity and risk taking. Learning and choice with delayed and uncertain reinforcement are related but in some cases dissociable processes. The contributions to delay and uncertainty discounting of neuromodulators including serotonin, dopamine, and noradrenaline, and of specific neural structures including the nucleus accumbens core, nucleus accumbens shell, orbitofrontal cortex, basolateral amygdala, anterior cingulate cortex, medial prefrontal (prelimbic/infralimbic) cortex, insula, subthalamic nucleus, and hippocampus are examined.}, author = {Cardinal, Rudolf N. }, booktitle = {Neurobiology of Decision Making}, citeulike-article-id = {882526}, doi = {http://dx.doi.org/10.1016/j.neunet.2006.03.004}, journal = {Neural Networks}, keywords = {discounting, rat, review, reward, risk, uncertainty}, month = {October}, number = {8}, pages = {1277--1301}, posted-at = {2006-10-04 18:17:31}, priority = {2}, title = {Neural systems implicated in delayed and probabilistic reinforcement}, url = {http://dx.doi.org/10.1016/j.neunet.2006.03.004}, volume = {19}, year = {2006} }
