ABSTRACT
This article focuses on the brain imaging. The two main brain imaging techniques discussed in this article are functional magnetic resonance imaging (fMRI) and positron emission tomography (PET). PET relies on the principle of detecting positron emitting radionuclides that are intravenously injected into a subject positioned so that the head is placed in a specialized detection system. fMRI produces images of active brain regions by detecting indirect effects of neural activity of local blood flow, volume, and oxygen saturation, giving detailed information regarding the functional neuroanatomy of the brain.
