Abstract

Recently, we found that electrical stimulation of motor cortex caused monkeys to make coordinated, complex movements. These evoked movements were arranged across the cortex in a map of spatial locations to which the hand moved. We suggest that some of the subdivisions previously described within primary motor and premotor cortex may represent different types of actions that monkeys tend to make in different regions of space. According to this view, primary and premotor cortex may fit together into a larger map of manual space.

摘要

最近，我们发现对运动皮层进行电刺激会使猴子做出协调的复杂动作。这些诱发动作在皮层上按照手部移动到的空间位置图谱进行排列。我们认为，先前在初级运动皮层和运动前区皮层中描述的一些亚区可能代表了猴子在不同空间区域倾向做出的不同类型动作。根据这一观点，初级运动皮层和运动前区皮层可能共同构成一个更大的手部空间图谱。
