Functional Magnetic Resonance Imaging (fMRI)

Functional magnetic resonance imaging (fMRI) is used to identify changes in neuronal function by physiological changes in blood flow and oxygen metabolism.

FMRI and magnetic resonance imaging (MRI) are noninvasive imaging techniques that use a magnetic field and radio wave energy to create images of areas inside the body. During fMRI, primates perform a particular task, causing increased metabolic activity in the area of the brain responsible for the task. Expanding blood vessels, chemical changes and the delivery of extra oxygen in the brain area responsible for the task, can then be recorded as an images. This is particularly helpful to Yerkes researchers studying addiction, human nature and evolution and stroke.
