自从“感觉”和“运动”皮质的概念首次被提出以来，感觉输入对运动皮质的影响程度一直是一个耐人寻味的问题。现在已经确定，猴子运动皮质中的单个细胞在短潜伏期被深度和皮肤刺激(2，6，26，46，48，49，51，66，68)激活；在某些情况下，这些细胞相对于运动的放电特性可能会受到外围干扰的影响(23，34)。短潜伏期的感觉输入不太可能只从感觉皮质到达运动皮质。Malis，Pribram和Kruger(54)记录了猴子的运动皮质，并表明刺激外周诱发的表面电位
Since the concept of a separate “sensory” and “motor” cortex was first developed, the extent to which sensory input influences the motor cortex has been an intriguing problem. It is now well established that single cells in the motor cortex of the monkey are activated at short latency by deep and cutaneous stimuli (2, 6, 26, 46, 48, 49, 51, 66, 68); under certain circumstances the discharge properties of these cells in relation to movement can be influenced by peripheral disturbances (23, 34). It is unlikely that short-latency sensory input reaches the motor cortex only from the sensory cortex. Malis, Pribram, and Kruger (54) recorded from the motor cortex of monkeys and showed that surface potentials, evoked by stimulating peripheral
