Abstract

We studied the effects of post-training intracranial electrical stimulation of the nucleus basalis magnocellularis on two-way active avoidance retention. After the acquisition, rats were stimulated for 20 min, and they were tested again after 24 h or 11 days. The treatment improved memory consolidation, especially in animals with a low initial learning ability. These facilitative effects could be attributed to an enhancement of cortical and/or amygdala activation, leading to an improvement in associative processes and/or cortical plasticity. © 2001 Elsevier Science B.V.
