The spatiotemporal evolution of cerebral microcirculatory adjustments to functional brain
stimulation is the fundamental determinant of the functional specificity of hemodynamically …

The precise modulation of regional cerebral blood flow during neural activation is important
for matching local energetic demand and supply and clearing brain metabolites. Here we …

The effect of direct cortical electrical stimulation on the pattern of erythrocyte perfusion in the
capillary network of the rat cerebral cortex was studied by fluorescence intravital video …

Cortical blood flow at the level of individual capillaries and the coupling of neuronal activity
to flow in capillaries are fundamental aspects of homeostasis in the normal and the diseased …

A close relationship exists between the local capillary density in different brain structures
and their local blood flow and metabolism. Capillary density appears to have developed …

Autoregulation of cerebral blood flow in the face of changing perfusion pressure has been
studied extensively; however, the precise degree to which flow in the microcirculation is …

Modern functional neuroimaging methods, such as positron-emission tomography (PET),
optical imaging of intrinsic signals, and functional MRI (fMRI) utilize activity-dependent …

The velocity of red blood cells (RBC) in individual capillaries of the rat cerebral cortex was
assessed using direct, intravital video microscopy under normal conditions and during …

The spatial and temporal response of the cerebral microcirculation to mild hypercapnia was
investigated via two-photon laser-scanning microscopy. Cortical vessels, traversing the top …

necessarily move in parallel. For example, increases in vascular diameter may be
accompanied by a decrease in blood pressure locally or systemically, result-ing either in no …
