Measurement of Neurovascular Coupling in Neonates [PDF]
Frontiers in Physiology, 2019 Neurovascular coupling refers to the mechanism that links the transient neural activity to the subsequent change in cerebral blood flow, which is regulated by both chemical signals and mechanical effects.

Vasculo-Neuronal Coupling and Neurovascular Coupling at the Neurovascular Unit: Impact of Hypertension [PDF]
Frontiers in Physiology, 2020 Components of the neurovascular unit (NVU) establish dynamic crosstalk that regulates cerebral blood flow and maintain brain homeostasis. Here, we describe accumulating evidence for cellular elements of the NVU contributing to critical physiological ...

Neurovascular Coupling in Development and Disease: Focus on Astrocytes
Frontiers in Cell and Developmental Biology, 2021 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 unit is responsible for activity-dependent changes in cerebral blood flow.

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: A Parallel Implementation [PDF]
Frontiers in Computational Neuroscience, 2015 A numerical model of neurovascular coupling (NVC) is presented based on neuronal activity coupled to vasodilation/contraction models via the astrocytic mediated perivascular K + and the smooth muscle cell (SMC) Ca2+ pathway termed a neurovascular unit ...

Disturbed neurovascular coupling in hemodialysis patients [PDF]
PeerJ, 2020 Background Altered cerebral blood flow (CBF) and amplitude of low-frequency fluctuation (ALFF) have been reported in hemodialysis patients. However, neurovascular coupling impairments, which provide a novel insight into the human brain, have not been ...
