Conference paper


With somatosensory evoked potentials (SEP) or evoked spinal cord potentials (ESCP) to the stimulation of each finger, it becomes possible to examine the sensory functions of clinically important dermatomes of C5/6–C8/T1 segments which can not be well evaluated by SEPs to peripheral nerve stimulation. The purpose of the present study is to obtain fundamental knowledge about somatotopical responses of the cervical cord or the cerebral cortex to finger stimulation.
