人类运动皮层与后顶叶皮层呈现不同的全身编码模式
Distinct patterns of whole-body coding in human motor cortex and posterior parietal cortex
AI 导读
Kadlec 等人在人类运动皮层和后顶叶皮层进行单神经元记录，发现这两个长期被认为主要控制手部运动的脑区，其神经元都对全身各部位的运动有反应。依据摘要，两区编码模式不同：运动皮层整体表现出效应器特异性，而后顶叶皮层对身体各部位的表征较为均等。该结果为理解人脑运动与躯体表征的脑区分工提供了单神经元层面的证据，样本量与统计细节需查阅全文。
摘要
Kadlec et al. record single neurons from two human brain regions long thought to control the hand and find that neurons in both areas respond to movements across the entire body. Overall effector specificity is observed in the motor cortex, while the parietal cortex represents every body part equally.
