Brain functional imaging

Brain functional imaging is a set of techniques used to visualize and measure brain activity. It helps scientists and doctors observe how different regions of the brain function in real time. Common methods include functional Magnetic Resonance Imaging (fMRI), which detects changes in blood flow, and Positron Emission Tomography (PET), which uses radioactive tracers to show metabolic activity. These techniques provide insights into brain functions related to emotions, cognition, and various neurological conditions, aiding research and improving diagnosis and treatment in fields like psychology and neurology.
