SPM (Statistical Parametric Mapping)

Our analysis software

SPM (Statistical Parametric Mapping)

The analytical methods we invent, develop, distribute, teach and use for testing hypotheses about functional anatomy from neuroimaging data are incorporated within our free and open statistical parametric mapping (SPM) software.

The software consists of a suite of tools for analysing brain imaging data, which may be images from different cohorts or time series from the same subject (fMRI, PET, EEG, MEG, etc).

SPM was originally conceived by Karl Friston in 1991 at the Positron Electron Tomography group at Hammersmith Hospital, before the group moved to Queen Square, London.

It was developed to provide a comprehensive assessment of differences throughout the brain, creating statistical parametric maps to test hypotheses about functional anatomy and has been shared openly since 1991. It is now one of the most popular tools for processing brain data globally, and supports a wide array of third party extensions expanding the core functionality to different imaging modalities, non-human brains, advanced analysis methods and clinical applications.

Throughout the years SPM has gone through many incarnations – the current software version is available here.
