Any technique that permits the invivo visualization of the substance of the central nervous system. These include: computerized axial tomography (CT) commonly called the CAT scan. Two other methods: positron-emission tomography (PET) and magnetic resonance imaging (MRI), based on different principles, also yield a series of two-dimensional images of brain regions.
technology used to create images of the structure or function of the brain; computed tomography, positron emission tomography, magnetic resonance imaging.
Techniques - Recently developed, noninvasive techniques for studying the activity of living brains. Includes brain electrical activity mapping (BEAM), computerized axial tomography (CAT), and magnetic resonance imaging (MRI).
This process involves taking pictures of the brain. The most recent technologies can take images of areas that are especially active while the brain is processing specific types of information, for example, sound or visual input. Three examples of the technology used in imaging are called Positron Emission Tomography (PET), functional Magnetic Resonance Imaging (FMRI), and computerized tomography (CAT scans). Analysis of the electroencephalogram (EEG) is another way to study brain activity.
Pictures of brains, such as functional MRIs, that can indicate activated parts of the brain.
