我们使用脑磁图进行实验，以阐明三维视觉空间能力和自发视觉思维特征之间的关系。根据心理旋转任务的正确率，被试被分为两组：表现好的(G组)和表现不好的(B组)。结果发现：(1)在心理旋转任务中，G组在顶上小叶/顶内沟区和枕颞区的25-35赫兹较低的γ频段活动显著大于B组；(2)在自发心理表象任务中，G组左侧运动前皮质的20-HZ频段活动和辅助运动区的35-HZ频段活动显著大于B组。
We performed experiments using magnetoencephalography to clarify the relationship between three-dimensional visuospatial abilities and spontaneous visual thinking characteristics. Subjects were divided into two groups based on the rate of correct answers to mental rotation tasks: those with good performances (Group G) and those with bad performances (Group B). We found the followings:(1) in the mental rotation tasks, the 25–35 Hz lower γ band activities in the superior parietal lobule/intraparietal sulcus regions and in the occipitotemporal region were significantly larger in Group G than in Group B and (2) in the spontaneous mental imagery tasks, the 20-Hz band activity in the left premotor cortex and the 35-Hz band activity in the supplementary motor area were significantly larger in Group G.
