Neuroimaging is a field of study that involves using various imaging technologies to visualize and understand the structure and function of the brain. This includes techniques such as MRI (magnetic resonance imaging), fMRI (functional MRI), EEG (electroencephalography), and PET (positron emission tomography). Neuroimaging is used in neuroscience research to investigate brain activity, connectivity, and abnormalities in various neurological and psychiatric disorders. It also has applications in clinical diagnosis, treatment planning, and monitoring of brain diseases and injuries. Overall, neuroimaging plays a crucial role in advancing our understanding of the human brain and how it relates to behavior and cognition.
