摘　　要：应用计算机技术及先进的大脑皮层电刺激仪等,进行了大脑皮层运动诱发电位的初步研究,对锥体束功能进行了直接定量测定,提供了有关运动负荷后锥体束及脊髓的兴奋变化情况,并以此为依据,对运动行为控制的神经生理基础及运动训练负荷最佳化提出了看法。The uninjuring quantity examination of the function of pyramidal system and peripheral nerve system is one of the new ways on neurophysiology research which developed in 1980's. The changes of the excitability of central nervous system before and after performance especially those of the direct control system of sparts-pyramidal function, remaina neurophysiological and psychological problem related to action behaviour and the control of action behaviour. It directly effects sports training, sports training pattern etc. Because of the limitation of the level of neuroelectrop-hysiology technology, the study on pyramidal function has not been done by anyone, at least the author of this article has not seen any report in this range till now. The author studied the pyramidal system function and directly examined it by use of computer. Based on full and accurate experiment data, the author first reported the excitability changes od pyramidal and spinal cord before and after performance and put forward a new view on neurophysiology foundation of action behaviour control and the projection on the best way of sports training pattern.
