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.
The human brain has billions of neurons. Working together, they enable higher-order brain functions such as cognition and complex behaviors. To study these higher-order brain functions, it is important to understand how neural ...
