BACKGROUND Adjuvant cancer treatments have been shown to decrease cardiac function. In addition to changes in cardiovascular risk, there are several additional functional consequences including decreases in exercise capacity and increased incidence of cancer-related fatigue. However, the effects of adjuvant cancer treatment on peripheral vascular function during exercise in cancer survivors hav...

To determine whether output from the forebrain (termed central command) may descend early enough to increase cardiac and renal sympathetic outflows at the onset of voluntary exercise, we examined the changes in regional tissue blood flows of bilateral prefrontal cortices with near-infrared spectroscopy, precisely identifying the onset of voluntary ergometer 30-s exercise at 41 ± 2% of the maxim...

UNLABELLED Studies have shown that dehydrated humans or animals in a warm environment begin to sweat within seconds to minutes after drinking. This phenomenon is one of the drinking-induced thermoregulatory responses; being investigated from different aspects. Our objective is to show the difference of voluntary drinking and imposed drinking in the methodology of these experiments. Six healthy ...

OBJECTIVE To investigate the role of the posterior thalamus in controlling voluntary and visually triggered eye movements and ocular fixation. METHODS The latency to initiate saccades to peripheral targets (visually triggered) and in response to verbal commands (voluntary) was measured in three patients with unilateral lesions of the posterior thalamus, in normal controls, and in neurological...

We have recently reported that central command contributes to increased blood flow in both noncontracting and contracting vastus lateralis (VL) muscles at the early period of voluntary one-legged cycling. The purpose of this study was to examine whether sympathetic cholinergic vasodilatation mediates the increases in blood flows of both muscles during one-legged exercise. Following intravenous ...
