dc.description.abstract |
Memory persistence in the inhibitory avoidance (IA) task has been recently shown to require a new
event of consolidation 12 hr after acquisition. The immobilization stress (IS) model is largely used
to study the effects of stress on memory. In this study we investigated the interactions between stress
by immobilization and its effect on the persistence of memory, and also a possible effect mediated
by -adrenergic modulation of stress on memory persistence. An enhancement of long-term memory
(LTM) persistence caused by stress through immobilization applied 12 hr after IA training was
observed when the animals were submitted to 15 min or 1 hr of IS, but not to 3 hr. The reversal of
this memory enhancement caused by IS was observed when the -adrenergic antagonist propranolol
was infused intraperitoneally prior to stress, which implies that -adrenergic receptors are involved
in stress enhancement of LTM persistence. |
