Experimental Physiology, EarlyView.Abstract Cerebral blood flow (CBF) is essential for sustaining neuronal metabolism and cognitive performance; however, the precise relationship between perfusion and cognition remains unclear. Although ageing and disease are associated with progressive declines in CBF and cognitive impairment, the acute effects of altered CBF under environmental ...

Human respiratory chemoreflex adaptations [PDF]
, 2004 Thus, adaptation in the chemoreflexes is shown here to be potentially beneficial in some cases, while exacerbating the pathology in other instances such as obstructive sleep apnoea.

eLife, 2015 Maintaining constant CO2 and H+ concentrations in the arterial blood is critical for life. The principal mechanism through which this is achieved in mammals is the respiratory chemoreflex whose circuitry is still elusive.

Oral contraceptives and menstrual cycle influence autonomic reflex function
Physiological Reports, 2020 Progesterone and its analogues are known to influence ventilation. Therefore, the purpose of this study was to investigate the role of endogenous and pharmaceutical female sex hormones in ventilatory control during the activation of the metaboreflex ...

Experimental Physiology, EarlyView.Abstract Central blood volume (CBV) reduction challenges circulatory and respiratory homeostasis, particularly during the initial compensatory phase (0–2 min), when rapid physiological adaptations occur. In this study, we examined dynamic cardiorespiratory responses to CBV reduction using lower‐body negative pressure (LBNP) in 11 healthy young males ...

Multireceptor activation of the pulmonary chemoreflex
, 1991 Schertel et al. (J. Appl. Physiol. 61: 1237–1240, 1984) reported that pulmonary C fibers initiate the prompt apnea followed by rapid shallow breathing evoked by pulmonary arterial injections of capsaicin.

Influence of facial cooling on carotid body tonic activity and sensitivity
Experimental Physiology, EarlyView.Abstract Facial cooling can increase ventilation and augment the hypoxic ventilatory response. Whole body cooling increases both carotid body tonic activity and sensitivity; however, whether isolated facial cooling induces similar carotid body hyperexcitability was unknown.

Malnutrition enhances cardiovascular responses to chemoreflex activation in awake rats.
, 2007 Several studies in the literature suggest that low-protein intake is associated with increases in sympathetic efferent activity and cardiovascular disease.

Nicotine increases chemoreflex sensitivity to hypoxia in non-smokers
, 2008 The peripheral chemoreflex contributes to cardiovascular regulation and represents the first line of defence against hypoxia. The effects of nicotine on chemoreflex regulation in non-smoking humans are unknown.Journal ArticleRandomized Controlled ...
