Using functional magnetic resonance imaging (fMRI) in humans, we identified regions of cortex involved in the encoding of limb position. Tactile stimulation of the right hand, across the body midline, activated the right parietal cortex when the eyes were closed; activation shifted to a left parietofrontal network when the eyes were open. These data reveal important similarities between human and non-human primates in the network of brain areas involved in the multisensory representation of limb position.
通过对人类使用功能磁共振成像（fMRI），我们确定了参与肢体位置编码的皮质区域。当眼睛闭合时，对右手穿过身体中线进行触觉刺激会激活右侧顶叶皮质；当眼睛睁开时，激活转移到左侧顶叶-额叶网络。这些数据揭示了人类和非人类灵长类动物在参与肢体位置多感觉表征的脑区网络方面的重要相似性。
