The cerebral microvasculature consists of pial vascular networks, parenchymal descending
arterioles, ascending venules and parenchymal capillaries. This vascular …

Optical imaging techniques reflect different biochemical processes in the brain, which is
closely related with neural activity. Scientists and clinicians employ a variety of optical …

The cortical microvessels are organized in an intricate, hierarchical, three-dimensional
network. Superimposed on this anatomical complexity is the highly complicated signaling …

Evaluation of spatiotemporal hemodynamic and metabolic responses during neural
activation is crucial in studying brain function. We explore the use of a noninvasive …

Brain functional connectivity based on the measure of blood oxygen level-dependent
(BOLD) functional magnetic resonance imaging (fMRI) signals has become one of the most …

Analysis of photon transit time for low-power light passing into the head, and through both
skull and brain, of human subjects allowed for tomographic imaging of cerebral hemoglobin …

While a range of cellular mechanisms have been proposed to underlie control of
neurovascular coupling, a comprehensive, reconciliatory model has yet to be determined …

Functional hyperemia, or the increase in focal perfusion elicited by neuronal activation, is
one of the primary functions of the neurovascular unit and a hallmark of healthy brain …

The cerebral vasculature provides blood flow throughout the brain, and local changes in
blood flow are regulated to match the metabolic demands of the active brain regions. This …

Connections between various cell types in the brain enable cognitive function. The
neurovascular unit is a structure composed of different cell types that regulate neurovascular …
