The central hypothesis is that emotionally arousing stimulation activates the amygdala and that activation results in modulation of the storage of acquired information. Although there is substantial evidence suggesting that memory storage, particularly storage of affective memory, may occur within the amygdala, other findings suggest that the amygdala influences memory storage occurring in other brain systems. Although studies of the effects of brain lesions have been important in efforts to understand the role of the amygdala in memory, interpretations of the findings of lesion studies are complicated by the fact that electrolytic, radio frequency, or neurotoxic lesions of the amygdala alter processes other than those directly involved in memory. Extensive evidence indicating that retention can be enhanced by posttraining administration of stimulant drugs suggests that memory storage may be modulated by the actions of endogenous neurotransmitters and hormones released by emotionally arousing stimulation. |
