Research Abstract

The present study demonstrated that early postnatal stress caused extinction deficit in adult rats, in which "critical period" exists during brain development. This extinction deficit appears to be associated with dysfunction of hippocampal CA1 field and/or medial prefrontal cortex(mPFC), because synaptic potentiation and ERK activation induced by extinction processes, in a brain specific manner, did not occur in juvenile stress model rats. This impaired synaptic plasticity and suppressed ERK activity, in addition to behavioral deficit were ameliorated by pretreatment with a NMDA receptor agonist D-cycloserine. These results suggest that the different phenotypes in adulthood result from neurodevelopmental perturbations of neural circuits of emotional regulation that elicited by early life stress.
