fMRI

fMRI is used to examine brain functions or activations. The active areas of the brain for specific tasks will  show enhancement from the increased oxygen in those areas of the brain. A given brain activation map can be elicited with a task paradigm designed by the researchers.

Functional MRI requires post-processing techniques after MRI data are collected.
