Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which neuroimaging method helps provide information about brain function by monitoring oxygen levels in the blood flow?
A
fMRI
B
MRI
C
EEG
D
MEG
Explanation: 

Detailed explanation-1: -Currently, the most widely used fMRI method is BOLD imaging, which detects the difference in magnetic susceptibility between oxygenated hemoglobin and deoxygenated hemoglobin.

Detailed explanation-2: -Functional magnetic resonance imaging (fMRI) measures the small changes in blood flow that occur with brain activity.

Detailed explanation-3: -FMRI is a method of measuring the flow of oxygenated blood in the brain (Ogawa et al., 1990A, 1990B; Bandettini, 1992). FMRI is based on the BOLD effect where BOLD stands for blood oxygen-level dependent.

Detailed explanation-4: -An fMRI scan is a special type of MRI that shows how different parts of your brain are working. They help doctors measure blood flow in the brain without having to do surgery. fMRI imaging is a safe, non-invasive way to diagnose conditions and to find out if certain treatments are working.

Detailed explanation-5: -Functional magnetic resonance imaging or functional MRI (fMRI) measures brain activity by detecting changes associated with blood flow. This technique relies on the fact that cerebral blood flow and neuronal activation are coupled. When an area of the brain is in use, blood flow to that region also increases.
