在精神应激状态下,中枢神经系统可能会发生结构可塑性的变化。相应的脑结构有:前额叶、杏仁核、海马、扣带回、后脑区、背缝核等。这些脑结构的可塑性变化有时是可逆的,有时是不可逆的,与应激损害的大小和持续时间长短有关系,当然也与个体的易感素质有关。本文重点介绍前额叶、 In psychic stress, changes in structural plasticity may occur in the central nervous system. The corresponding brain structure are: prefrontal cortex, amygdala, hippocampus, cingulate gyrus, posterior cerebral area, dorsal raphe nucleus and so on. Changes in the plasticity of these brain structures are sometimes reversible, sometimes irreversible, and the size and duration of stress damage have a relationship, of course, with the individual’s susceptibility to quality. This article focuses on the frontal lobe,
