Further evidence for latent learning in hippocampal-lesioned rats.

ABSTRACT

Rats with substantial dorsolateral lesions to the hippocampal formation showed significant latent learning of a complex spatial maze. Their overall maze performance, however, was characteristically impaired. Behavior during the pre-exposure phase of the experiment was useful in predicting test maze behavior. Three measures in particular had predictive value entrances into the maze alley leading to the final choice point, behavior at that choice point, and goal box entries.
