体性感覚誘発応答の電子回路モデルによる検討

抄録

  We measured somatosensory evoked fields (SEFs) obtained by electric stimulation to the right thumb with a39-channel SQUID system. To investigate the relationship between phase lag and stimulus repetition frequency, the delay time of a component synchronized with the stimulus repetition frequencies was calculated by convoluting the reference signal and the measured SEF. We also simulated electronic circuit model to obtain SEF function.. Finally we modeled SEF responses. We presented that characteristic of SEFs between phase lag and stimulus repetition frequency by using electronic circuit.
