Neurovascular coupling is the term used to describe alterations in local perfusion that occur in response to changes in neuronal activity. Mechanisms of neurovascular coupling The neurovascular unit is made up of three major components. Neurovascular coupling reflects the close temporal and regional linkage between neural activity and cerebral blood flow. It has previously been shown that neurovascular coupling is similar across awake arousal states Winder et al 2017 and that both spontaneous and sensory-evoked hemodynamics are most strongly correlated with gamma band power and multi-unit average MUA a measure of local spiking activity in the absence of overt stimulation Mateo et al. In the past technical constraints have restricted investigations of neurovascular coupling to cortical sites and have led to the assumption that coupling in non-cortical structures is the same as in the cortex despite the lack of any evidence. Laminar Differences in Neurovascular Coupling For positive BOLD responses.

CBF decreased superficially while CBV increased in the center. We measured neurovascular coupling in the dorsal CA1 region of the HC and in V1 of head-fixed mice expressing GCaMP6f in excitatory glutamatergic neurons 13Mice could run on a running cylinder. Mechanisms of neurovascular coupling The neurovascular unit is made up of three major components. NeuroVascular Coupling NVC is the connection between neurons and their vascular supply which is their energy source required to function properly. In the past technical constraints have restricted investigations of neurovascular coupling to cortical sites and have led to the assumption that coupling in non-cortical structures is the same as in the cortex despite the lack of any evidence. 1 the vascular smooth muscle 2 the neuron and 3 the astrocyte glial cell Figure 1.

At a rudimentary level of detail modulations in neuronal activity cause changes in local blood flow mediated by transmission through the astrocyte. Neurovascular coupling is the phenomenon by which blood flow to different parts of the brain is regulated in a second-to-second fashion in response to the metabolic needs of the tissue as we all have become aware through familiarity with functional MRI. For negative BOLD responses. Optical neuroimaging is a major focus of our lab and in particular we are seeking to use our imaging systems to better understand. Essentially NVC is what allows the brain to work and function.

NeuroVascular Coupling NVC is the connection between neurons and their vascular supply which is their energy source required to function properly. Neurovascular coupling also termed functional hyperemia is one of the physiological key mechanisms to adjust blood flow in a neural tissue in response to functional activity. We previously reported altered cerebrovascular responses during functional hyperemia in chronically stressed animals.
