A comparative evaluation of acute stress and corticosterone on the process of learning and emotional memory in rat

Previous studies suggested that stressful events that release Glucocorticoid from adrenal cortex and also injection of agonists of glucocorticoids receptors probably affect emotional learning and memory process and modulate them. The aim of this study was to determine the effects of acute stress and systemic injection of Corticosterone (as agonist of glucocorticoid receptors) on acquisition (ACQ), consolidation (CONS) and retrieval (RET) of emotional memory in rat. In this experimental study we used 180 male Wistar rats (220-250). At the first rats was training in one trial inhibitory
