Sympathetic neural responses to mental stress during acute simulated microgravity.
Neural and cardiovascular responses to mental stress and acute 6 degrees head-down tilt (HDT) were examined separately and combined. We hypothesized sympathoexcitation during mental stress, sympathoinhibition during HDT, and an additive neural interaction during combined mental stress and HDT. Muscle sympathetic nerve activity (MSNA), mean arterial pressure (MAP), and heart rate (HR) were recor...
متن کاملEffects of hyperinsulinemia on sympathetic responses to mental stress.
In a recent study, we could not find evidence to support the hypothesis that insulin activates the sympathetic nervous system (SNS) during a hyperinsulinemic glucose clamp procedure. Mental stress tests (MST), however, may be used to detect differences in blood pressure and SNS activity that are not present during baseline or resting conditions. In this study, we aimed to investigate the effect...
متن کاملSympathetic neural responses to mental stress: responders, nonresponders and sex differences.
Mental stress consistently increases heart rate (HR) and blood pressure (BP) in humans, despite inconsistent sympathetic neural responses that include increases, decreases, or no change in muscle sympathetic nerve activity (MSNA). The purpose of the present study was to examine associations between MSNA, BP, and HR responses to mental stress. Leg MSNA, BP, HR, and perceived stress levels were r...
متن کاملInfluence of acute alcohol ingestion on sympathetic neural responses to orthostatic stress in humans.
Acute alcohol consumption is reported to decrease mean arterial pressure (MAP) during orthostatic challenge, a response that may contribute to alcohol-mediated syncope. Muscle sympathetic nerve activity (MSNA) increases during orthostatic stress to help maintain MAP, yet the effects of alcohol on MSNA responses during orthostatic stress have not been determined. We hypothesized that alcohol ing...
متن کاملRenal responsiveness to aldosterone during exposure to simulated microgravity.
We measured renal functions and hormones associated with fluid regulation after a bolus injection of aldosterone (Ald) during head-down tilt (HDT) bed rest to test the hypothesis that exposure to simulated microgravity altered renal responsiveness to Ald. Six male rhesus monkeys underwent two experimental conditions (HDT and control, 72 h each) with each condition separated by 9 days of ambulat...
