The brain circuitry underlying emotion includes several territories of the prefrontal cortex (PFC), the amygdala, hippocampus, anterior cingulate, and related structures. In general, the PFC represents emotion in the absence of immediately present incentives and thus plays a crucial role in the anticipation of the future affective consequences of action, as well as in the persistence of emotion following the offset of an elicitor. The functions of the other structures in this circuit are also considered. Individual differences in this circuitry are reviewed, with an emphasis on asymmetries within the PFC and activation of the amygdala as 2 key components of affective style. These individual differences are related to both behavioral and biological variables associated with affective style and emotion regulation. Plasticity in this circuitry and its implications for transforming emotion and cultivating positive affect and resilience are considered.
情绪背后的脑回路包括前额叶皮层（PFC）的几个区域、杏仁核、海马体、前扣带回及相关结构。一般来说，前额叶皮层在没有即时出现的诱因时表征情绪，因此在预测行动的未来情感后果以及诱因消失后情绪的持续方面起着关键作用。该回路中其他结构的功能也在考虑范围内。文中回顾了该脑回路的个体差异，重点关注前额叶皮层内的不对称性以及杏仁核的激活，将其作为情感风格的两个关键组成部分。这些个体差异与情感风格和情绪调节相关的行为及生物学变量都有关系。文中还考虑了该脑回路的可塑性及其对转变情绪、培养积极情感和恢复力的影响。
