A patient with acquired, pathologic left-handed mirror writing and mirror movements during bimanual coordination is reported. CT demonstrated an ischemic infarction involving the right supplementary motor area, medial prefrontal cortex, and anterior cingulate gyrus with nearly total sparing of the corpus callosum. This case, together with recent experimental findings in monkeys, supports the hypothesis that the supplementary motor area may be responsible for nonmirror transformation of motor programs originating in the left hemisphere prior to execution by the primary motor area in the right hemisphere.
报告了一名患有后天性病理性左手镜像书写及双手协调时镜像运动的患者。CT显示右侧辅助运动区、内侧前额叶皮质和前扣带回发生缺血性梗死，而胼胝体几乎完全未受影响。该病例与近期猴子实验结果共同支持了这样一种假说，即辅助运动区可能负责在右半球初级运动区执行之前，对源自左半球的运动程序进行非镜像转换。
