Hormones influence many physiological systems involved in regulating adaptation to environmental changes. In addition to their many other influences, hormones serve an adaptive role in regulating the neurobiological processes underlying memory formation and other cognitive processes. Extensive evidence indicates that, in laboratory animals, hormones administered shortly after training influence the retention of recently acquired information. Although many hormones either enhance or impair long-term retention when administered after training, the effects of hormones normally released by mildly stressful stimulation have been studied most extensively. The findings suggest that endogenous hormones released by emotionally arousing training experiences influence long-term memory by modulating memory consolidation processes. In addition to such acute effects, hormones may also have more sustained effects on cognition through neurotrophic and neuroprotective actions.
