A computational model of hippocampal function in trace conditioning
2008
Neural Information Processing Systems

We introduce a new reinforcement-learning model for the role of the hippocampus in classical conditioning, focusing on the differences between trace and delay conditioning. ...
In the model, all stimuli are represented both as unindividuated wholes and as a series of temporal elements with varying delays. ...
In this paper, we present a new abstract computational model of hippocampal function during trace conditioning. ...
