With the growing recognition of the complexity of neurovascular coupling, research has
focused on the “neurovascular unit”, a close association between neurons, astrocytes and …

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 …

Neurovascular coupling refers to the relationship between local neural activity and
subsequent changes in cerebral blood flow (CBF). The magnitude and spatial location of …

Functional hemodynamic responses, measured by methods such as fMRI or optical imaging,
are the composite, downstream results of underlying variations in cerebral oxygen …

Functional neuroimaging using MRI relies on measurements of blood oxygen level-
dependent (BOLD) signals from which inferences are made about the underlying neuronal …

The current understanding of fMRI, regarding its vascular origins, is based on numerous
assumptions and theoretical modeling, but little experimental validation exists to support or …

The brain consumes approximately a quarter of the body's total glucose and a fifth of the
oxygen, much more than what would be expected on a weight basis. This remarkable …

The amount of information acquired with functional neuroimaging techniques, particularly
fNIRS and fMRI, is rapidly growing and has enormous potential for studying human brain …

In the neocortex, neurons with similar response properties are often clustered together in
column‐like structures, giving rise to what has become known as functional architecture …

We make a few additional points regarding our discussion with Sirotin and Das' 2009 Nature
paper and their 2011 NeuroImage response to our commentary. While we find their data …
