The current study used functional magnetic resonance imaging to examine the neural activity of an expert dancer with 35 years of break-dancing experience during the kinesthetic motor imagery (KMI) of dance accompanied by highly familiar and unfamiliar music. The goal of this study was to examine the effect of musical familiarity on neural activity underlying KMI within a highly experienced dancer. In order to investigate this in both primary sensory and motor planning cortical areas, we examined the effects of music familiarity on the primary auditory cortex [Heschl's gyrus (HG)] and the supplementary motor area (SMA). Our findings reveal reduced HG activity and greater SMA activity during imagined dance to familiar music compared to unfamiliar music. We propose that one's internal representations of dance moves are influenced by auditory stimuli and may be specific to a dance style and the music accompanying it.
当前的研究使用功能磁共振成像来检测一位拥有35年霹雳舞经验的专业舞者在伴随着非常熟悉和不熟悉音乐的舞蹈动觉运动想象（KMI）过程中的神经活动。本研究的目的是检验音乐熟悉度对一位经验丰富的舞者KMI潜在神经活动的影响。为了在初级感觉和运动规划皮层区域对此进行研究，我们检测了音乐熟悉度对初级听觉皮层[颞横回（HG）]和辅助运动区（SMA）的影响。我们的研究结果显示，与不熟悉的音乐相比，在想象伴随着熟悉音乐的舞蹈时，HG活动减少，SMA活动增强。我们提出，一个人对舞蹈动作的内部表征会受到听觉刺激的影响，并且可能特定于一种舞蹈风格及其伴随的音乐。
