Optical approaches to investigate cerebral function and metabolism have long been applied
in invasive studies. From the neuron cultured in vitro to the exposed cortex in the human …

Functional magnetic resonance imaging (fMRI) has allowed the noninvasive study of task-
based and resting-state brain dynamics in humans by inferring neural activity from blood …

Near-infrared spectroscopy (NIRS) has been used to noninvasively monitor adult human
brain function in a wide variety of tasks. While rough spatial correspondences with maps …

The potential for human neuroimaging to read out the detailed contents of a person's mental
state has yet to be fully explored. We investigated whether the perception of edge …

Background Simultaneous intracortical recordings of neural activity and blood-oxygen-level-
dependent (BOLD) functional magnetic resonance imaging (fMRI) in primary visual cortex of …

Haemodynamic signals underlying functional brain imaging (for example, functional
magnetic resonance imaging (fMRI)) are assumed to reflect metabolic demand generated by …

Anesthesia has broad actions that include changing neuronal excitability, vascular reactivity,
and other baseline physiologies and eventually modifies the neurovascular coupling …

One of the major limitations in the current set of techniques available to neuroscientists is a
dearth of methods for imaging individual cells deep within the brains of live animals. To …

Propofol, a short-acting intravenous anaesthetic agent has gained wide acceptance since its
introduction in the late 80s, not only in operating rooms but also in other departments, due to …

Intrinsic signal imaging from inferotemporal (IT) cortex, a visual area essential for object
perception and recognition, revealed that visually presented objects activated patches in a …
