The uses of various techniques to either directly or indirectly image the structure, function/pharmacology of the nervous system. It has two categories- structural imaging and functional imaging. Structural imaging, which deals with the structure of the nervous system and the diagnosis of gross (large scale) intracranial disease (such as a tumor), and injury. Functional imaging, which is used to diagnose metabolic diseases and lesions on a finer scale (such as Alzheimer's disease) and also for neurological and cognitive psychology research and building brain-computer interfaces.
Neuroimaging is the process of producing images of the structure or activity of the brain or another part of the nervous system by techniques such as magnetic resonance imaging or computerized tomography.
