MRI (Magnetic Resonance Imaging): This imaging technique uses strong magnetic fields and radio waves to generate detailed images of the brain's structure.
fMRI (Functional Magnetic Resonance Imaging): fMRI measures changes in blood flow within the brain, allowing researchers to observe brain activity associated with specific tasks or stimuli.
PET (Positron Emission Tomography): PET scans involve injecting a radioactive tracer into the body which is then detected by a scanner. It shows areas of high metabolic activity in the brain, providing information about its function.
