Neurovascular Coupling in Seizures
Neuroglia, 2021 Neurovascular coupling is a key control mechanism in cerebral blood flow (CBF) regulation. Importantly, this process was demonstrated to be affected in several neurological disorders, including epilepsy. Neurovascular coupling (NVC) is the basis for functional brain imaging, such as PET, SPECT, fMRI, and fNIRS, to assess and map neuronal activity, thus

Mechanisms of neurovascular coupling
Regional blood circulation and microcirculation, 2023 The brain is characterized by a well-developed vascular network and consumes a significant proportion of cardiac output relative to its mass. Normally, the metabolic needs of the brain significantly depend on the intensity of the functioning of its various departments, which requires constant regulation of the level of local blood flow.

Changes in Hemodynamic Responses in Chronic Stroke Survivors Do Not Affect fMRI Signal Detection in a Block Experimental Design [PDF]
, 2013 The use of canonical functions to model BOLD-fMRI data in people post-stroke may lead to inaccurate descriptions of task-related brain activity. The purpose of this study was to determine whether the spatiotemporal profile of hemodynamic responses (HDRs)

Toward three-dimensional in vitro models to study neurovascular unit functions in health and disease
Neural Regeneration Research, 2021 The high metabolic demands of the brain require an efficient vascular system to be coupled with neural activity to supply adequate nutrients and oxygen. This supply is coordinated by the action of neurons, glial and vascular cells, known collectively as ...
