Evaluation of the hypothesis that phasic dopamine constitutes a cached-value signal
2018
Neurobiology of Learning and Memory
The phasic dopamine error signal is currently argued to be synonymous with the prediction error in Sutton and Barto (1987 Barto ( , 1998 model-free reinforcement learning algorithm (Schultz et al., 1997) .
