fMRI
Functional Magnetic Resonance Imaging (fMRI) is a brain imaging technique that measures brain activity by detecting changes in blood flow.
It provides real-time data on brain function and activity, which helps in understanding how different brain regions interact.
Like the standard MRI, its scan uses an extremely powerful magnet, radio waves and computer processing
generate highly detailed 3D pictures, but is special because it tracks blood flow in different parts of your brain
How It Works
fMRI tracks changes in blood oxygenation levels, which reflect neural activity.
Increased brain activity leads to increased blood flow in that area.
During an fMRI scan, electrical activity and blood flow in the brain are monitored, producing detailed images of brain function.
Researchers use fMRI to identify abnormal brain patterns in depression.
These patterns help in categorizing different subtypes of depression, potentially guiding more effective treatments.
