The examples of Functional Neuroimaging include fMRI, PET, and SPECT.
Functional Magnetic Resonance Imaging (fMRI)
An fMRI assesses the metabolic activity in an area of the nervous system with associated neural activity. It is one of the least expensive methods and one of the more commonly used methods in neuropsychological research.
Positron Emission Topography (PET)
PET scan produces a realtime image of an area of the brain after a radionuclide is injected into the bloodstream. PET scan measures the emissions from the radionuclide after an area of the brain is activated.
Single-Photon Emission Computerized Tomography (SPECT)
SPECT scans utilize a gamma camera that rotates around the individual and takes scans from different angles. These images are then used to create a cross-sectional (tomographic) image.
