The evoked skin potential reflex (SPR) to a 1-sec tone (80dB, 1000Hz) was examined on ten subjects during sleep. The magnitude of evoked SPR was larger than that of spontaneous SPR, and the per cent appearance of SPR showed a cyclic decrease and SPR was never absent in any sleep stages. Thus, contrary to previous studies, there was little inhibition of evoked SPR during sleep. Like spontaneous SPR, the evoked SPR showed the regional differences in waveform and in magnitude between the palm and the dorsal hand but there was no relation between sleep stages and SPR variables. The mechanisms underlying the evoked SPR would be too complex to be explained by a simple disinhibition model, and would involve some psychophysiological functions.
