Neuroimaging (fMRI, PET)

Neuroimaging is a set of techniques used to visualize and understand brain activity. Functional Magnetic Resonance Imaging (fMRI) measures changes in blood flow in the brain, indicating areas that are more active during certain tasks. Positron Emission Tomography (PET) scans involve injecting a small amount of radioactive material that highlights active brain areas based on their metabolism. Both methods help researchers and doctors see how the brain functions, aiding in the study of disorders, understanding cognitive processes, and assessing brain health. They provide valuable insight without needing invasive procedures.
