The author discusses a neurological model of a modular network that mediates emotional experience. According to this theory, emotional experience has three components: valence (positive and negative), arousal, and motor activation (approach, avoid, neither). In this model, the cortex is critical in regulating activities of the limbic system, basal ganglia, and reticular system. The frontal lobes are important for valence: the left mediates positive emotions, the right negative emotions. The right hemisphere, especially the parietal lobe, is important in activating arousal systems, and the left hemisphere modulates inhibition of these systems. The right hemisphere is also critical in motor activation. The frontal lobes, especially the orbitofrontal portions, mediate avoidance behaviors, and the parietal lobes mediate approach behaviors. The cortical areas discussed have rich interconnections and are also closely connected with the limbic system, basal ganglia, and reticular systems. Emotional experience may depend on the patterns of neural activation in this modular network.
作者讨论了一个介导情感体验的模块化网络的神经学模型。根据这一理论，情感体验有三个组成部分：效价（积极和消极）、唤醒和运动激活（趋近、回避、两者皆非）。在这个模型中，皮层对于调节边缘系统、基底神经节和网状系统的活动至关重要。额叶对效价很重要：左侧介导积极情绪，右侧介导消极情绪。右半球，尤其是顶叶，在激活唤醒系统方面很重要，而左半球调节这些系统的抑制。右半球在运动激活方面也很关键。额叶，尤其是眶额部分，介导回避行为，而顶叶介导趋近行为。所讨论的皮层区域有丰富的相互连接，并且也与边缘系统、基底神经节和网状系统紧密相连。情感体验可能取决于这个模块化网络中的神经激活模式。
