The effect of radical hippocampal ablation on acquisition of avoidance response.

Abstract
Rats with hippocampal lesions were compared to normal rats and rats with cortical lesions in a shuttle-box situation. Animals were trained for 5 days, with extinction trials preceding shock trials on Days 2 to 5. Operates reached the learning criterion most rapidly; they showed lower latencies in extinction as well as on learning trials. (PsycINFO Database Record (c) 2006 APA, all rights reserved)
