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.
When Darwin Quiroz first started working with optics as an undergraduate, he was developing atomic magnetometers. That experience sparked a growing curiosity about how light interacts with matter, an interest that has now ...
