杏仁核和杏仁核被认为是帮助评价和情感过程的中枢网络的组成部分，尽管它们的确切作用还没有完全阐明。本研究探讨了评价价和唤醒评级图片刺激的患者与病变的杏仁核或。获得了对图片刺激的积极性、消极性和唤醒性的评级（从非常消极到非常积极）。杏仁核的病变并没有改变积极或消极的效价评级，但与衰减的唤醒评级的负面刺激。与此相反，岛叶病变的患者表现出减少觉醒的消极和积极的刺激，以及相应的效价评级显着衰减。结果支持的观点，岛叶皮层可能发挥更广泛的作用，在整合情感和认知过程，而杏仁核可能有更多的选择性作用，在情感唤醒，特别是对负性刺激。
The insula and the amygdala have been implicated as components of central networks subserving evaluative and affective processes, although their precise contributions have not been fully elucidated. The present study examined evaluative valence and arousal ratings to picture stimuli in patients with lesions of the insula or the amydala. Ratings of positivity, negativity and arousal to picture stimuli (extending from very negative to very positive) were obtained. Lesions of the amygdala did not alter either positive or negative valence ratings, but were associated with attenuated arousal ratings for negative stimuli. In contrast, patients with insular lesions displayed reduced arousal to both negative and positive stimuli, as well as marked attenuation of corresponding valence ratings. Results support the view that the insular cortex may play a broader role in integrating both affective and cognitive processes, whereas the amygdala may have a more selective role in affective arousal, especially for negative stimuli.
