Coherent Structures in Ocean Skin Temperature Variability

Sympathetic skin response and heart rate variability in predicting autonomic disorders in patients with Parkinson disease

The purpose of this study was to evaluate sympathetic skin response (SSR) and heart rate variability (HRV) in determining autonomic nervous system (ANS) involvement in patients with Parkinson disease (PD). Forty-eight idiopathic PD patients and 30 healthy controls participated in this study. SSR, HRV, Unified Parkinson's Disease Rating Scale (UPDRS) III, the Scales for outcomes in Parkinson's D...

Skin blood flow and local temperature independently modify sweat rate during passive heat stress in humans.

Sweat rate (SR) is reduced in locally cooled skin, which may result from decreased temperature and/or parallel reductions in skin blood flow. The purpose of this study was to test the hypotheses that decreased skin blood flow and decreased local temperature each independently attenuate sweating. In protocols I and II, eight subjects rested supine while wearing a water-perfused suit for the cont...

Variability of skin temperature in the waking monkey.

Temperatures of the brain, skin, and nasal mucosa were recorded along with the cortical electroencephalogram (EEG) in chaired, conscious pigtail monkeys at 25 degrees C air temperature. In undisturbed animals, skin temperatures ranged from 34 to 37 degrees C. When the animal was alerted by visual or auditory stimuli, temperatures on the extremities, tail, nose, ears, and nasal mucosa dropped ra...

Characterizing human skin blood flow regulation in response to different local skin temperature perturbations.

Small nerve fibers regulate local skin blood flow in response to local thermal perturbations. Small nerve fiber function is difficult to assess with classical neurophysiological tests. In this study, a vasomotor response model in combination with a heating protocol was developed to quantitatively characterize the control mechanism of small nerve fibers in regulating skin blood flow in response ...
