| Research Abstract |
Somatosensory cortical responses following electrical stimulation to the median nerve or finger were studied non-invasively by the electromagnetic recording method. We, for the first time, succeeded in visualizing impulse propagations along the fibers from the thalamus to the somatosensory cortex with the mean conduction velocity of 29 m/s. Also, we have shown that the 600 Hz high frequency oscillations (HFOs), overlying initial cortical activity, reflect the function of inhibitory interneurons as the initial step of somatosensory information processing in the primary somatosensory cortex.
