The Bimodal Nature of Neurovascular Coupling
Neurons, by virtue of their complex and continuously changing signaling roles in brain, must be able to regulate access to energy in order to maintain their ability to communicate meaningful frequency-encoded information. This is accomplished by release of neurotransmitters to astrocytes that in turn signal the vascular system to increase cerebral blood flow (CBF). This process has been termed ...
متن کاملNeurovascular Coupling Studies in Awake-behaving Mice
The mechanism regulating cerebral blood fl ow (CBF) during brain function (neurovascular coupling) has been widely investigated in animals under anesthetized conditions, though anesthesia is known to greatly aff ect neurovascular physiology. The present study aims to develop a novel model for neurovascular coupling studies in awake-behaving mice. Male C57BL/6J mice were initially anesthetized w...
متن کاملNeurovascular coupling in cognitive impairment associated with diabetes mellitus.
Although it is feared that diabetes-induced cognitive decline will become a major clinical problem worldwide in the future, the detailed pathological mechanism is not well known. Because patients with diabetes have various complications of vascular disease, with not only macrovascular but also microvascular disorders, vascular disorders in the brain are considered to be one of the mechanisms in...
متن کاملNeurovascular coupling - Scholarpedia
Neurovascular coupling refers to the relationship between local neural activity and subsequent changes in cerebral blood flow (CBF). The magnitude and spatial location of blood flow changes are tightly linked to changes in neural activity through a complex sequence of coordinated events involving neurons, glia, and vascular cells. Many vascular-based functional brain imaging techniques, such as...
متن کاملRole of Astrocytes in Neurovascular Coupling
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. We highlight unresolved issues regarding the...
