SPM techniques

Statistical Parametric Mapping (SPM) is a set of techniques used to analyze brain imaging data, like MRI scans, to detect areas of activity, differences, or changes. It involves creating detailed statistical maps that highlight regions with significant variations, helping researchers understand brain functions or identify abnormalities. SPM processes the images through steps like normalization (aligning images to a standard brain template), smoothing (reducing noise), and statistical testing to pinpoint meaningful differences across groups or conditions. Overall, it transforms complex imaging data into understandable maps that reveal important insights about brain structure and activity.
