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: 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 ...

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.

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 ...

Neurovascular coupling in bone regeneration
Experimental & Molecular Medicine, 2022 AbstractThe mammalian skeletal system is densely innervated by both neural and vascular networks. Peripheral nerves in the skeleton include sensory and sympathetic nerves. The crosstalk between skeletal and neural tissues is critical for skeletal development and regeneration.

Arousal state transitions occlude sensory-evoked neurovascular coupling in neonatal mice
Communications Biology, 2023 In the adult sensory cortex, increases in neural activity elicited by sensory stimulation usually drive vasodilation mediated by neurovascular coupling.

Neurovascular coupling in the mammalian brain [PDF]
Experimental Physiology, 2007 Normal brain function requires proper supply of oxygen and glucose in a timely and local manner. This is achieved through an orchestrated intercellular communication between neurones, astrocytes and microvessels that results in a rapid and restricted increase in cerebral blood flow, a process known as neurovascular coupling.

Altered resting-state neurovascular coupling in patients with pontine infarction
Experimental Gerontology, 2023 The risk for motor and cognitive impairment is increased in patients with chronic pontine infarction (PI). In this study, we attempted to explore the alterations of neurovascular coupling (NVC) in order to understand the neural basis of behavioral ...

Role of Astrocytes in Neurovascular Coupling [PDF]
Neuron, 2011 Neural activity is intimately tied to blood flow in the brain. This coupling is specific enough in space and time that modern imaging methods use local hemodynamics as a measure of brain activity. In this review, we discuss recent evidence indicating that neuronal activity is coupled to local blood flow changes through an intermediary, the astrocyte ...

Neurovascular dysfunction in vascular dementia, Alzheimer’s and atherosclerosis
BMC Neuroscience, 2018 Efficient blood supply to the brain is of paramount importance to its normal functioning and improper blood flow can result in potentially devastating neurological consequences.
