Emotional memory: Effects of corticosterone on aversive memories

摘要: The adrenal hormones administered immediately before or after a learning task modulate memory. This effect varies according to time and intensity with which hormones increase. The release or administration of glucocorticoids 0before or after a task, facilitate memory. Althought, the elevation of glucocorticoids before a test of learning deteriorates evocation of information previously learned. This paper presents a review of the animal and human studies on the role of glucocorticoids on the memory of aversive events. Also, this paper presents a description about the effect of acute and chronic elevation of adrenal hormones on memory.
