functional magnetic resonance imaging (fMRI)
Functional magnetic resonance imaging (fMRI) is a non-invasive imaging technique used to measure and map brain activity. It detects changes in blood flow and oxygen levels in the brain, which are linked to neural activity. When a specific area of the brain is more active, it requires more oxygen, leading to increased blood flow to that region.
Researchers use fMRI to study brain functions, understand neurological disorders, and explore cognitive processes. It has applications in various fields, including psychology, neuroscience, and medicine, helping scientists and doctors gain insights into how the brain works and how it responds to different stimuli or conditions.
