Bodily abnormalities in other persons often evoke an uneasy feeling, even disgust. Here, we studied the brain basis of such perceptual salience by presenting static pictures of distorted hand postures to healthy subjects during functional magnetic resonance imaging. Cortical activation sensitive to distorted (vs. natural) finger postures was found-with right-hemispheric dominance-in the primary motor cortex, postcentral somatosensory areas, amygdala, and insula, and bilaterally in the putamen. This activation pattern suggests that the instantaneous "gut feelings" during the observation of bodily distortions in others are related to embodied percepts that also involve affect-related brain areas.
他人身体的异常往往会引起一种不安的感觉，甚至是厌恶。在这里，我们通过在功能磁共振成像期间向健康受试者呈现扭曲的手姿势的静态图片来研究这种感知突显的大脑基础。研究发现，在初级运动皮层、后中央体感区域、杏仁核和脑岛中，对扭曲（与自然）手指姿势敏感的皮质激活存在右侧半球优势，并且在壳核中双侧存在。这种激活模式表明，在观察他人身体扭曲时的即时“直觉”与涉及与情感相关的大脑区域的体现感知有关。
