Stroke. Tumors. Brain injury from trauma. A special type of MRI is the functional MRI of the brain, also known as fMRI. It produces images of blood flow to certain areas of the brain. Functional MRI can be used to examine the brain's anatomy and show which parts of the brain are handling critical functions, language and movements.
Yarkoni (2009) suggests that sample sizes of 20 subjects used in many current fMRI studies are much too small and sample sizes of 50 or larger are most likely more appropriate to detect the effects in fMRI.
