Magnetic Resonance Imaging (MRI): This technique uses magnetic fields and radio waves to create detailed images of the brain's structure.
Positron Emission Tomography (PET): PET scans involve injecting a small amount of radioactive substance into the body, which highlights areas with increased activity in the brain.
Functional Magnetic Resonance Imaging (fMRI): fMRI measures changes in blood flow to detect active regions in the brain during specific tasks or activities.
