Stress response regulation and the hemodynamic response [PDF]
Proceedings of the National Academy of Sciences, 2018 Stress is among the most important risk factors for a variety of mood and anxiety disorders (1, 2), but the underlying neurobiological mechanisms remain incompletely understood, especially in humans. Previous human neuroimaging studies have identified a network of brain regions that exhibit increased activity and blood flow in response to acute ...

Hemodynamic Responses during Enduro-Motorcycling Performance [PDF]
Frontiers in Physiology, 2017 Much of the information available in the literature on physiological responses during Enduro motorcycling is related to heart rate (HR) and blood lactate (BLa). The aim of this work was to investigate the hemodynamic changes that occur during a 10-min session of Enduro motorcycling. Fifteen skilled riders were enrolled on the study and all participants

Journal of Anaesthesiology Clinical Pharmacology, 2011 Background : Drug combinations can be used for optimum obtundation of the hemodynamic response to tracheal intubation. The objective of this trial was to compare the hemodynamic response to laryngoscopy and tracheal intubation after administration of 2 ...

Comparability of Functional MRI Response in Young and Old During Inhibition [PDF]
, 2004 When using fMRI to study age-related cognitive changes, it is important to establish the integrity of the hemodynamic response because, potentially, it can be affected by age and disease.

Exercise intolerance and fatigue in chronic heart failure: is there a role for group III/IV afferent feedback? [PDF]
, 2020 Exercise intolerance and early fatiguability are hallmark symptoms of chronic heart failure. While the malfunction of the heart is certainly the leading cause of chronic heart failure, the patho-physiological mechanisms of exercise intolerance in these ...

Hemodynamically informed parcellation of cerebral FMRI data [PDF]
, 2014 Standard detection of evoked brain activity in functional MRI (fMRI) relies on a fixed and known shape of the impulse response of the neurovascular coupling, namely the hemodynamic response function (HRF).

HRF estimation improves sensitivity of fMRI encoding and decoding models [PDF]
, 2013 Extracting activation patterns from functional Magnetic Resonance Images (fMRI) datasets remains challenging in rapid-event designs due to the inherent delay of blood oxygen level-dependent (BOLD) signal. The general linear model (GLM) allows to estimate
