Neurovascular coupling mechanisms in health and neurovascular uncoupling in Alzheimer's disease

WM Zhu, A Neuhaus, DJ Beard, BA Sutherland… - Brain, 2022 - academic.oup.com
To match the metabolic demands of the brain, mechanisms have evolved to couple neuronal
activity to vasodilation, thus increasing local cerebral blood flow and delivery of oxygen and …

[HTML][HTML] Pericyte-mediated regulation of capillary diameter: a component of neurovascular coupling in health and disease

NB Hamilton, D Attwell, CN Hall - Frontiers in neuroenergetics, 2010 - frontiersin.org
Because regional blood flow increases in association with the increased metabolic demand
generated by localised increases in neural activity, functional imaging researchers often …

[HTML][HTML] Multifunctional role of astrocytes as gatekeepers of neuronal energy supply

JL Stobart, CM Anderson - Frontiers in cellular neuroscience, 2013 - frontiersin.org
Dynamic adjustments to neuronal energy supply in response to synaptic activity are critical

[HTML][HTML] Neurovascular coupling in development and disease: focus on astrocytes

TL Stackhouse, A Mishra - Frontiers in cell and developmental biology, 2021 - frontiersin.org
Neurovascular coupling is a crucial mechanism that matches the high energy demand of the
brain with a supply of energy substrates from the blood. Signaling within the neurovascular …

[HTML][HTML] What is the key mediator of the neurovascular coupling response?

PS Hosford, AV Gourine - Neuroscience & Biobehavioral Reviews, 2019 - Elsevier
The mechanisms of neurovascular coupling contribute to ensuring brain energy supply is
sufficient to meet demand. Despite significant research interest, the mechanisms underlying …

Beyond neurovascular coupling, role of astrocytes in the regulation of vascular tone

JA Filosa, HW Morrison, JA Iddings, W Du, KJ Kim - Neuroscience, 2016 - Elsevier
