A neural substrate of prediction and rewardW Schultz
Institute of Physiology, University of Fribourg, CH 1700 Fribourg, Switzerland
Science 275:1593-9. 1997..Taken together, these findings can be understood through quantitative theories of adaptive optimizing control...- Multiple reward signals in the brainW Schultz
Institute of Physiology and Program in Neuroscience, University of Fribourg, CH 1700 Fribourg, Switzerland
Nat Rev Neurosci 1:199-207. 2000..This research provides the first step towards an understanding of how rewards influence behaviour before they are received and how the brain might use reward information to control learning and goal-directed behaviour... - Reward signaling by dopamine neuronsW Schultz
Institute of Physiology and Program in Neuroscience, University of Fribourg, Switzerland
Neuroscientist 7:293-302. 2001..The dopamine reward prediction error signal may cooperate with these reward perception signals during the learning and performance of behavioral reactions to motivating environmental stimuli... - Neuronal coding of prediction errorsW Schultz
Institute of Physiology, University of Fribourg, Switzerland
Annu Rev Neurosci 23:473-500. 2000..The coding of prediction errors may represent a basic mode of brain function that may also contribute to the processing of sensory information and the short-term control of behavior... - Reward processing in primate orbitofrontal cortex and basal gangliaW Schultz
Institute of Physiology and Program in Neuroscience, University of Fribourg, CH 1700 Fribourg, Switzerland
Cereb Cortex 10:272-84. 2000..The processing of reward expectations suggests an access to central representations of rewards which may be used for the neuronal control of goaldirected behavior... - Reward prediction in primate basal ganglia and frontal cortexW Schultz
Institute of Physiology and Program in Neuroscience, University of Fribourg, Switzerland
Neuropharmacology 37:421-9. 1998..These reward signals need to cooperate in order for reward information to be used for learning and maintaining approach behavior... - Dopamine neurons and their role in reward mechanismsW Schultz
Institute of Physiology, University of Fribourg, 1700 Fribourg, Switzerland
Curr Opin Neurobiol 7:191-7. 1997..These reward-related responses correspond formally to concepts of behavioral and computational learning theories and may thus constitute teaching signals for appetitive learning... - Involvement of basal ganglia and orbitofrontal cortex in goal-directed behaviorJ R Hollerman
Institute of Physiology, Universite de Fribourg, Switzerland
Prog Brain Res 126:193-215. 2000..These activations would serve a function similar to those striatal neurons that encode exclusively reward-related information in situations in which only a single outcome is obtainable. (ABSTRACT TRUNCATED).. - Dopamine responses comply with basic assumptions of formal learning theoryP Waelti
Institute of Physiology and Programme in Neuroscience, University of Fribourg, CH-1700 Fribourg, Switzerland
Nature 412:43-8. 2001..Our data indicate that the use of analytical tests derived from formal behavioural learning theory provides a powerful approach for studying the role of single neurons in learning... - Temporal difference model reproduces anticipatory neural activityR E Suri
Institut de Physiologie, 1700 Fribourg, Switzerland
Neural Comput 13:841-62. 2001..This finding suggests that tonic anticipatory activities may reflect prediction signals that are involved in the processing of dopamine neuron activity... - Influence of expectation of different rewards on behavior-related neuronal activity in the striatumO K Hassani
Institute of Physiology, University of Fribourg, CH-1700 Fribourg, Switzerland
J Neurophysiol 85:2477-89. 2001..The results of this study are in general agreement with an account of goal-directed behavior according to which the outcome should be represented already at the time at which the behavior toward the outcome is performed...
