Cholinergic mechanisms of the context preexposure facilitation effect in adolescent rats.

abstract：:In previous studies the cerebellar interpositus (IP) nucleus, but not the hippocampus, was shown to be necessary both for initial learning and retention and for long-term retention of the standard delay eyeblink conditioned response (CR). However, in the trace eyeblink CR procedure, the hippocampus is also necessary f...
