Neuroimaging

Definition
noun
The application of the various techniques to generate images showing activity, structure, and function of the brain or other parts of the nervous system
Supplement
Neuroimaging is the use of the different techniques to generate images depicting the activity, structure, and function of the brain or other parts of the nervous system. It is one of the techniques utilized in research studies in neuroscience. Neuroscience is the scientific study of the nervous system and is concerned with the structure, development, function, chemistry, pharmacology, and pathology of the nervous system. Modern tools and technologies (e.g. molecular biology, electrophysiology, computational methods, etc.) led to the advancement of research on nervous system.
Neuroimaging is a relatively new discipline. There are two major categories: (1) structural imaging and (2) functional imaging. In structural imaging, the structure of the nervous system is the focus. In functional imaging, it uses neuroimaging technology in order to measure an aspect of brain function.
Computed axial tomography, diffuse optical imaging, event-related optical signal, magnetic resonance imaging, functional magnetic resonance imaging, magnetoencephalography, positron emission tomography, single-photon emission computed tomography, and cranial ultrasound are some of the neuroimaging technologies used in neuroscience research (e.g. in cognitive neuroscience)
