Brain imaging encompasses various techniques used to visualize and understand the structure, function, and connectivity of the brain. These methods include magnetic resonance imaging (MRI), functional MRI (fMRI), positron emission tomography (PET), electroencephalography (EEG), and magnetoencephalography (MEG). By applying these techniques in the context of neural networks, researchers can investigate how different brain regions work together to process information and generate behavior. Brain imaging thereby offers a crucial window into the neural mechanisms underlying cognition, emotion, and disease, and facilitates the development of targeted interventions for neurological and psychiatric disorders.
