Brain imaging is a field of scientific research that involves using various techniques to capture images of the brain's structure and function. This includes methods such as magnetic resonance imaging (MRI), positron emission tomography (PET), computed tomography (CT), and electroencephalography (EEG). These imaging techniques can provide valuable insights into the brain's anatomy, neural activity, and connectivity, and are used in a wide range of research areas including neuroscience, psychology, and medicine. Brain imaging is instrumental in the study of neurological disorders, cognitive processes, and brain development, and continues to advance our understanding of the complex workings of the human brain.
