Effects of Stress on Learning and Memory

Research output: Chapter in Book/Report/Conference proceedingChapter

Abstract

Memories are sometimes enhanced by stress and at other times diminished. A unified conceptual framework is herein developed to identify the circumstances in which these opposing effects of stress are likely to be seen. Significant contributory factors appear to be the nature of the stressor, the nature of the learning task, and the relationship between the two. Stimulation of glucocorticoid receptors and activation of the amygdala are common to both types of effect. The challenge of future research is to further characterize downstream mechanisms that determine how these neural responses to stress promote or prevent memory formation under different circumstances.
