A tight coupling between the neuronal activity and the cerebral blood flow (CBF) is the
motivation of many hemodynamic response (HR)-based neuroimaging modalities. The …

The difference between awake curarized and α-chloralise anesthetized animals was studied
with respect to the BOLD signal response in an fMRI experiment. By studying the activation …

The spatial resolution of hemodynamic-based neuroimaging techniques, including
functional magnetic resonance imaging, is limited by the degree to which neurons regulate …

Using optical methods through a closed cranial window over the rat primary sensory cortex
in chloralose/urethane-anesthetized rats we evaluated the time course of oxygen delivery …

Inhibitory interneurons can evoke vasodilation and vasoconstriction, making them potential
cellular drivers of neurovascular coupling. However, the specific regulatory roles played by …

This research investigates the hemodynamic response to stimulation of the barrel cortex in
anaesthetized rats using optical imaging and spectroscopy (Bonhoeffer and Grinvald, 1996; …

Billions of neurons in the human brain form neural networks with oscillation rhythms. Infra-
slow oscillation (ISO) presents three main physiological sources: endogenic, neurogenic …

By means of noninvasive near-infrared spectroscopy (NIRS), cerebral concentration
changes in oxygenated and deoxygenated hemoglobin ([oxy-Hb] and [deoxy-Hb]) can be …

Using the modified Lambert-Beer law to analyze attenuation changes measured
noninvasively during functional activation of the brain might result in an insufficient …

These are exciting times for the field of optical imaging of brain function. Rapid
developments in theory and technology continue to considerably advance understanding of …
