Statistical Parametric Mapping (SPM)

Statistical Parametric Mapping (SPM) is a technique used to analyze brain images, like those from MRI or PET scans. It helps scientists and clinicians identify areas of brain activity or differences between groups by applying statistical tests across the entire brain. Essentially, SPM creates detailed maps highlighting regions where significant changes or patterns occur, allowing for precise interpretation of brain function or abnormalities. It standardizes the process of analyzing complex imaging data, making it easier to understand how different parts of the brain are involved in various tasks or affected by diseases.
