Abstract

This pilot study attempted to identify a relationship between dance and mirror neuron activity in people with Parkinson's disease by investigating Mu rhythm desynchronization in electroencephalographic (EEG) data before and after regular participation in a program of dance classes. During the EEG recordings, the participants observed a sequence of videos showing either choreographic (complex) or daily (simple) movements, each preceded by a baseline image (dark screen) and a control video (moving blocks). The results showed a statistically significant increase in Mu rhythm desynchronization in the alpha 1 band at the central channels after 6 months of dance classes. Control comparisons with occipital channels showed no such increase. Mu rhythm suppression has been demonstrated to reflect the activity of the human mirror neuron system, respond to variations in motor expertise, and seem to be impaired in Parkinson's disease. The Mu wave desynchronization increase shown here, after 6 months of dance classes, is an objective measurement of the benefits of such practice for people with Parkinson's disease (PD).

帕金森病患者舞蹈课后Mu波不同步增加。

这项初步研究试图通过调查定期参加舞蹈课程前后脑电图（EEG）数据中的Mu节律不同步，来确定帕金森病患者跳舞与镜像神经元活动之间的关系。在EEG记录期间，参与者观察了一系列视频，显示舞蹈（复杂的）或日常（简单的）动作，每个动作之前都有一个基线图像（暗屏幕）和一个控制视频（移动块）。结果显示，在6 个月的舞蹈课程后，中央通道α 1带的Mu节律不同步有统计学意义的增加。枕部通道的对照没有这种增加。Mu节律抑制已被证明反映了人类镜像神经元系统的活动，对运动专长的变化做出反应，并且似乎在帕金森病中受损。在6个 个月的舞蹈课程后，图中显示的Mu波不同步增加是对帕金森病患者（PD）这种练习的好处的客观衡量。

期刊介绍： Frontiers in Human Neuroscience is a first-tier electronic journal devoted to understanding the brain mechanisms supporting cognitive and social behavior in humans, and how these mechanisms might be altered in disease states. The last 25 years have seen an explosive growth in both the methods and the theoretical constructs available to study the human brain. Advances in electrophysiological, neuroimaging, neuropsychological, psychophysical, neuropharmacological and computational approaches have provided key insights into the mechanisms of a broad range of human behaviors in both health and disease. Work in human neuroscience ranges from the cognitive domain, including areas such as memory, attention, language and perception to the social domain, with this last subject addressing topics, such as interpersonal interactions, social discourse and emotional regulation. How these processes unfold during development, mature in adulthood and often decline in aging, and how they are altered in a host of developmental, neurological and psychiatric disorders, has become increasingly amenable to human neuroscience research approaches. Work in human neuroscience has influenced many areas of inquiry ranging from social and cognitive psychology to economics, law and public policy. Accordingly, our journal will provide a forum for human research spanning all areas of human cognitive, social, developmental and translational neuroscience using any research approach.
