Short-term Modulation of Scalp Acupuncture on Cortical Excitability and Motor-related Cortical Potential
头皮针短暂调解皮质应激性与动作准备电位的作用

This study was aimed to investigate short-term modulation mechanism of scalp acupuncture according to the experimentation of cortical excitability and motor -related cortical potentials in ten normal volunteers. Through scalp needle stimulation in specific theoretical areas related to underlying cerebral surfaces, scalp acupuncture can be used as an effective therapy by changes in relative cerebral function, which is the basic principle. According to the available neurophysiological data in our study, the modulation of scalp acupuncture displayed in late part of motor-related cortical potential noticed mainly in the motor and sensory cortexes, contralateral to the needle stimulate site. Also, acupuncture can develop inhibition at longer interstimulus intervals, in paired pulse magnetic stimulation, from the somatosensory input of contralateral sensory cortex via scalp needle stimulation. In our study, it might be difficult to produce more acupuncture inhibition. The maintaining of scalp needles subcutaneously without other management after achieving needling sensations cannot achieve the requested strength of the acupuncture stimulation.
