Divergent short- and long-term effects of acute stress in object recognition memory are mediated by endogenous opioid system activation

Acute stress induces short-term object recognition memory impairment and elicits endogenous opioid system activation. The aim of this study was thus to evaluate whether opiate system activation mediates the acute stress-induced object recognition memory changes. Adult male Wistar rats were trained i...
