Development of measurement system for brain function dynamics by using magneto-encephalography and transcranial magnetic stimulation

在这项研究中，我们开发了一套系统，用于研究周围神经电刺激引起的传入信号与运动皮质经颅磁刺激(TMS)产生的传出信号之间的关系。利用所研制的系统研究了传入信号和传出信号之间的动态关系。结果提示，初级体感皮层电流偶极子的激活和方向与传入信号对运动功能的影响有关。

In this study, we developed a system for investigation of the relationship between the afferent signals elicited by an electrical stimulus of a peripheral nerve and the efferent signals produced by a transcranial magnetic stimulation (TMS) of the motor cortex by using magneto-encephalography (MEG). The dynamic relation between the afferent and efferent signals was investigated by using the system we developed. The results suggested that the activation and direction of the current dipole in the primary somatosensory cortex was related to the effect of the afferent signals on the motor function.
