A number of hormones secreted from the pituitary—adrenal system during stress affect
learning and memory processes. The phenomenon of hippocampal long-term potentiation
(LTP) is viewed by many as a putative mechanism of memory storage and has proved a
most valuable model for study of neuronal plasticity at the cellular level. The present study
was conducted to investigate the possibility that stressful events which occur prior (in vivo) to
the preparation of brain slices may influence the electrophysiology of the in vitro …
