Detailed explanation-1: -Since MRI scans show brain anatomy, it would be the best scan to determine the size of a particular area in the brain.
Detailed explanation-2: -These technological methods include the encephalogram (EEG), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI) and positron emission tomography (PET). These techniques ultimately have the same goal in that they aim to produce coherent representations of the brain.
Detailed explanation-3: -A form of MRI known as functional MRI (fMRI) has emerged as the most prominent neuroimaging technology over the last two decades. fMRI tracks changes in blood flow and oxygen levels to indicate neural activity. When a particular brain area is more active, it consumes more oxygen, and blood flow increases.
Detailed explanation-4: -Advanced noninvasive neuroimaging techniques such as EEG and fMRI allow researchers to directly observe brain activities while subjects perform various perceptual, motor, and/or cognitive tasks.
Detailed explanation-5: -Magnetic Resonance Imaging (MRI)
