| Research Abstract |
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.
