Neuroimaging is a suite of in vivo techniques used to noninvasively visualize and quantify structural, functional, and molecular properties of the nervous system, primarily the brain. Major modalities include magnetic resonance imaging (MRI) and its derivatives (fMRI, DTI), positron emission tomography (PET), single-photon emission computed tomography (SPECT), magnetoencephalography (MEG), and electroencephalography (EEG) when used with anatomical imaging. These techniques enable measurement of brain morphology, connectivity, hemodynamics, metabolism, receptor binding, and electrophysiological activity, supporting research on neural circuit organization, disease mechanisms, pharmacodynamics, and biomarkers, as well as multimodal data integration for advanced computational and statistical modeling of brain function.
Near-infrared spectroscopy, or fNIRS, offers a way to monitor brain activity without surgery or radiation by tracking changes in blood flow and oxygenation. Light sources placed on the scalp send near-infrared light into ...

A recent study published in Physical Review Letters reveals that many widely used signatures of criticality in brain data may be statistical artifacts. They propose a more robust framework that, when applied to whole-brain ...
Cerebral blood flow is essential for normal brain function and often perturbed in neurological disease. If one shines a source of coherent light on perfused tissue, the detected speckles, or "grains" of light fluctuate, or ...
