Neuroimaging measures structural or functional properties of the nervous system. Different methods record different physical signals, so anatomical images and activity-sensitive measurements support different inferences.
For example, electroencephalography records electrical potential differences, while many functional vascular measurements depend on neurovascular coupling. Spatial overlap in an image is not by itself proof that one location implements a complete psychological process.
Neuroimaging refers to a variety of techniques used to visualize the structure, function, and activity of the brain and nervous system. These methods allow researchers and clinicians to observe the brain in both healthy and diseased states, aiding in the understanding of its anatomy, functioning, and the pathology of neurological and psychiatric disorders.
