functional neuroimaging
Brain imaging techniques that measure brain activity and function rather than just structure.
Full Definition
Functional neuroimaging encompasses brain imaging methods that visualize and measure brain activity, metabolism, and function in real time, rather than simply depicting anatomical structure. These techniques include functional magnetic resonance imaging (fMRI), positron emission tomography (PET), and single-photon emission computed tomography (SPECT). Functional neuroimaging is invaluable in neuropsychiatric research and clinical practice for understanding brain mechanisms underlying mental disorders, tracking treatment effects, and identifying biomarkers for psychiatric conditions.
