To investigate central conduction time, somatosensory evoked potentials(SEPs) were recorded simultaneously from the spine and the scalp in 31 normal young korean adults using median and posterior tibial nerve stimulation. We determined somatosensory central conduction time(CCT) in each subject from peak-to-peak and onset-to-onset measurement. The bandpass were 10~1000Hz for the spinal and 10~3000Hz for the scalp recording. The mean value for the peak CCT was 5.71±0.48 msec and for the onset CCT was 5.83±0.78 msec in median nerve SEPs and 16.99+1.60 msec in posterior tibial nerve SEPs. There were not significant correlation between the CCTs and subjects height.
