Hippocampal aspiration lesions fail to impair performance of a delayed alternation GO/NO-GO task.
Rats with hippocampal aspiration lesions (HIPP), cortical control lesions (CORT) or sham operations (SHAM) were trained on a delayed alternation GO/NO-GO task, in which responding was reinforced on odd-numbered GO trials but was not reinforced on even-numbered NO-GO trials. The number of responses required to obtain reinforcement, and the length of the inter-trial intervals (ITIs), were varied in different stages of the experiment. These systematic parametric manipulations were conducted in o...Expand abstract
