Key result
Skin sympathetic nerve activity exhibits low-frequency and high-frequency oscillations that are coherent with corresponding variability in R-R interval and systolic pressure, similar to muscle sympathetic nerve activity.
Population
18 healthy male volunteers, aged 30 ± 3 years (range 22–35 years), nonsmokers, not on medications.

Extends evidence for shared central sympathetic regulation; hypothesis-generating for skin SNA in autonomic research and should not yet change practice.
Observational (n=18)
Skin sympathetic nerve activity exhibits low- and high-frequency oscillations similar to muscle sympathetic nerve activity, suggesting common central mechanisms regulate sympathetic outflows to different regions.
Cogliati et al. (2000) conducted an observational in Healthy (n=18). Microneurography of skin and muscle sympathetic nerve activity was evaluated on Low-frequency (LF) and high-frequency (HF) spectral components in SSNA variability. Skin sympathetic nerve activity exhibits low-frequency and high-frequency oscillations that are coherent with corresponding variability in R-R interval and systolic pressure, similar to muscle sympathetic nerve activity.
