现代舞训练与弦乐训练对脑灰质体积的差异影响

目前舞蹈与音乐两种训练对脑灰质结构影响的差异尚不明确。本研究利用基于体素的形态学分析方法(voxel-based morphometry, VBM), 比较现代舞训练被试、弦乐训练被试与对照组被试的脑结构磁共振数据。结果表明现代舞训练组在涉及感觉运动控制的皮层、皮层下结构及小脑多个区域出现灰质体积的显著增加与减少; 弦乐训练组则在与音乐训练直接相关的听-动-读皮层出现灰质体积的显著增加。这一发现提示现代舞训练可能系统性地影响广泛脑区的灰质结构, 弦乐训练可能局部地改变了具体功能脑区的灰质结构, 两种训练对脑灰质结构的影响模式存在差异。

Modern dance training and string instrument training have different effects on grey matter architecture

The discrepant effects of dance and music training on gray matter volume are still unknown. In this study, We used voxel-based morphometry (VBM) method to analyze the structural magnetic resonance imaging (sMRI) data of modern dancers, string instrument players and controls subjects. Our results showed increased gray matter volume (GMV) among cortical, subcortical and the cerebellum areas within the modern dancers and localized cortical regions in the string instrument players respectively. Moreover, among the three groups only modern dancers showed decreased GMV between cortical and subcortical regions. The results suggested a systematical and widespread effects of modern dance training as well as an effector-specific training outcome in the auditory-motor-semantic cortex of the string instrument players.
