fMRI

Functional magnetic resonance imaging (fMRI) is a neuroimaging technique that measures and maps brain activity by detecting changes associated with blood flow. This method relies on the fact that cerebral blood flow and neuronal activation are coupled; when an area of the brain is in use, blood flow to that region also increases. fMRI is particularly valuable in psychology and cognitive neuroscience because it allows researchers to observe the brain while it is processing information, thereby helping to identify which parts of the brain are involved in specific mental processes. Non-invasive and requiring no exposure to radiological agents, fMRI has become a fundamental tool in the understanding of brain functions, aiding in clinical diagnosis and medical research.
