Resting-state functional MRI and structural MRI were used to study correlations of spontaneous activity and gray matter density between the left and right primary sensorimotor areas in pianists and nonmusicians. Functional MRI analysis showed significant correlation of spontaneous activity between the left and right primary sensorimotor area in both groups; however, there was no between-group difference. Structural MRI analysis showed significant correlation in gray matter density between the left and right sensorimotor areas in nonmusicians (r=0.65, P=0.001), but not in pianists (r=0.07, P=0.78), with a significant between-group difference (P=0.035). The lack of correlation of gray matter density between the left and right sensorimotor areas might be the basis of bimanual coordination of the pianists.
静息态功能磁共振成像（fMRI）和结构磁共振成像（MRI）被用于研究钢琴演奏者和非音乐家左右初级感觉运动区之间自发活动和灰质密度的相关性。功能磁共振成像分析显示，两组中左右初级感觉运动区之间的自发活动存在显著相关性；然而，组间无差异。结构磁共振成像分析显示，非音乐家左右感觉运动区之间的灰质密度存在显著相关性（r = 0.65，P = 0.001），而钢琴演奏者中则无（r = 0.07，P = 0.78），组间差异显著（P = 0.035）。左右感觉运动区之间灰质密度缺乏相关性可能是钢琴演奏者双手协调的基础。
