Although aging is associated with clear declines in physical and cognitive processes, emotional functioning fares relatively well. Consistent with this behavioral profile, two core emotional brain regions, the amygdala and ventromedial prefrontal cortex, show little structural and functional decline in aging, compared with other regions. However, emotional processes depend on interacting systems of neurotransmitters and brain regions that go beyond these structures. This review examines how age-related brain changes influence processes such as attending to and remembering emotional stimuli, regulating emotion, and recognizing emotional expressions, as well as empathy, risk taking, impulsivity, behavior change, and attentional focus.
尽管衰老与身体和认知功能的明显衰退相关,但情绪功能相对保持良好。与这种行为特征一致的是,两个核心情绪脑区,即杏仁核和腹内侧前额叶皮层,与其他脑区相比,在衰老过程中结构和功能衰退较少。然而,情绪过程依赖于超越这些结构的神经递质和脑区相互作用系统。本文综述了与年龄相关的脑变化如何影响诸如关注和记忆情绪刺激、调节情绪、识别情绪表达等过程,以及共情、冒险、冲动、行为改变和注意力焦点。
