There are two views regarding the role of the amygdala in emotional memory formation. According to one view, the amygdala modulates memory-related processes in other brain regions, such as the hippocampus. According to the other, the amygdala is a site for some aspects of emotional memory. Here the authors adduce behavioral, electrophysiological, and biochemical evidence in support of an integrative view, assuming both roles for the amygdala. This integrative view, however, suggests a level of complexity not referred to before: the assumption that emotional conditions induce long-term neural plasticity in the amygdala suggests that the interrelations between the amygdala and brain regions, such as the hippocampus, may not be static but dynamic. The way the amygdala will affect memory-related processes in the hippocampus may thus largely depend on the previous history of the individual.
关于杏仁核在情绪记忆形成中的作用，存在两种观点。一种观点认为，杏仁核对其他脑区（如海马体）中与记忆相关的过程起调节作用。另一种观点则认为，杏仁核是情绪记忆某些方面的发生部位。本文作者列举了行为学、电生理学和生物化学方面的证据，以支持一种综合观点，即认为杏仁核兼具这两种作用。然而，这种综合观点意味着一种前所未有的复杂程度：情绪状态会在杏仁核中诱导长期神经可塑性这一假设表明，杏仁核与海马体等脑区之间的相互关系可能并非静态，而是动态的。因此，杏仁核影响海马体中与记忆相关过程的方式可能在很大程度上取决于个体之前的经历。
