Research news on Neuroimaging

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.

A layered approach sharpens brain signals in optical imaging

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 ...

Seals and sea lions provide clues to evolution of vocalization

Neuroscientists have uncovered new insights into a key evolutionary question: Why can humans talk when most animals can't? The journal Science published the research led by Emory University and the New College of Florida. ...
