Abstract

We recorded skin sympathetic nerve activity (SSNA), SSR, and SVR in 30 subjects. SSNA and SVR showed a slight decrease and spontaneous changes in resting SSR were significantly less frequent in older subjects compared with younger subjects (p < 0.05). There was no significant relationship between age and the reflex latency or amplitude of SSNA, SSR, and SVR in response to electrical stimulation.
