Neurovascular coupling in the healthy and inflamed brain [PDF]

The structural and functional integrity of the brain relies on a close balance between the metabolic demands of neurons and supporting glia, and substrate delivery in the form of blood flow.

Ictal but not interictal epileptic discharges activate astrocyte endfeet and elicit cerebral arteriole responses.

Frontiers in Cellular Neuroscience, 2011
Activation of astrocytes by neuronal signals plays a central role in the control of neuronal activity-dependent blood flow changes in the normal brain.

Neurobarrier Coupling in the Brain: A Partner of Neurovascular and Neurometabolic Coupling? [PDF]

Journal of Cerebral Blood Flow & Metabolism, 2005
Neurovascular and neurometabolic coupling help the brain to maintain an appropriate energy flow to the neural tissue under conditions of increased neuronal activity. Both coupling phenomena provide us, in addition, with two macroscopically measurable parameters, blood flow and intermediate metabolite fluxes, that are used to dynamically image the ...

Is Neurovascular Coupling of Relevance in Glaucoma?

, 2014
. Rapid development of functional neuroimaging techniques have brought about a growing interest for neurovascular coupling in neuroresearch, which, in turn, has prompted similar research in ophthalmology.

Cerebral blood flow and functional connectivity immediate changes following intradermal acupuncture in major depressive disorder

Frontiers in Neuroscience
BackgroundAcupuncture has been increasingly applied as an adjunctive treatment for major depressive disorder (MDD), yet its central neurobiological mechanisms remain insufficiently understood.

TRPV4 channels stimulate Ca2+-induced Ca2+ release in astrocytic endfeet and amplify neurovascular coupling responses

, 2013
In the CNS, astrocytes are sensory and regulatory hubs that play important roles in cerebral homeostatic processes, including matching local cerebral blood flow to neuronal metabolism (neurovascular coupling).

Analysis of neurovascular coupling in migraneours

Zdravniški Vestnik, 2005
Background: According to recent data it is not clear whether neurovascular coupling is disturbed in migraneours during headache free period. The aim of our study was to establish whether the relationship between visually evoked cerebral blood flow ...
