人类镜像系统参与音乐情绪的自动加工：来自EEG的证据

The human mirror system (HMS) consists of a core parietofrontal network of regions in the inferior parietal lobule and inferior frontal gyrus/premotor cortex, which can be activated by action observation and execution. Mu rhythm suppression is considered an electrophysiological indicator of the HMS given their similarity in reaction to action observation and execution. Mu rhythm comprises α (8–13 Hz) and β (15–25 Hz) frequency bands, which are typically measured at the power change of midline electrode sites. The β frequency band is related to the movement preparation, whereas the α frequency band is suppressed during the execution of movement. Consistent with the role of the HMS in social cognition, such as emotion understanding, theory of mind, and empathy, mu rhythm suppression is modulated by the processing of social information, such as facial emotional information. Emotion is an important component of social communication. In addition to the emotional facial expression, music is an effective means of ex
