The effects of hemodynamic lag on functional connectivity and behavior after stroke [PDF]
, 2015 Stroke disrupts the brain's vascular supply, not only within but also outside areas of infarction. We investigated temporal delays (lag) in resting state functional magnetic resonance imaging signals in 130 stroke patients scanned two weeks, three months

Analysis of Pain Hemodynamic Response Using Near-Infrared Spectroscopy (NIRS) [PDF]
The International Journal of Multimedia & Its Applications (IJMA)
Vol. 7, No. 2, April 2015, 2015 Despite recent advances in brain research, understanding the various signals for pain and pain intensities in the brain cortex is still a complex task due to temporal and spatial variations of brain hemodynamics. In this paper we have investigated pain based on cerebral hemodynamics via near-infrared spectroscopy (NIRS).

Hemodynamic profiles of functional and dysfunctional forms of repetitive thinking [PDF]
, 2016 Background: The ability of the human brain to escape the here and now (mind wandering) can take functional (problem solving) and dysfunctional (perseverative cognition) routes.

Hemodynamic response in the motor cortex to execution of different types of movements [PDF]
Известия высших учебных заведений: Прикладная нелинейная динамика, 2022 Purpose of this work is the analysis of the hemodynamic response to the execution of various types of movements (single movement, series of movements, “tapping”) by the right hand. Methods. In this paper, the hemodynamic response was recorded

The role of mechano-electric feedbacks and hemodynamic coupling in scar-related ventricular tachycardia [PDF]
arXiv, 2021 Mechano-electric feedbacks (MEFs), which model how mechanical stimuli are transduced into electrical signals, have received sparse investigation by considering electromechanical simulations in simplified scenarios. In this paper, we study the effects of different MEFs modeling choices for myocardial deformation and nonselective stretch-activated ...

Higher ventricular rate during atrial fibrillation relates to increased cerebral hypoperfusions and hypertensive events [PDF]
Scientific Reports, 9: 3779, 2019, 2019 Atrial fibrillation (AF) is associated with cognitive impairment/dementia, independently of clinical cerebrovascular events (stroke/TIA). One of the plausible mechanisms is the occurrence of AF-induced transient critical hemodynamic events; however, it is presently unknown, if ventricular response rate during AF may impact on cerebral hemodynamics.

Activity in the Visual Cortex is Modulated by Top-Down Attention Locked to Reaction Time [PDF]
, 2007 We studied the correlation between perception and hemodynamic activity in the visual cortex in a change detection task. Whenever the observer perceived the location of a change, rightly or wrongly, the blood oxygenation level-dependent signal increased ...
