Statistical parametric mapping (SPM) has recently become a popular method for investigating the spatial distribution of brain activity in studies using fMRI and PET. In addition, the coregistration procedure transforms the PET data set and so introduces errors. It is assumed that the observed data set is sampled from a larger population.. Inferential statistics can be contrasted with descriptive statistics. Statistical parametric maps calculated from MEG during a verbal size judgement task are shown of the noise-normalized anatomically constrained dipole amplitudes. Statistical parametric maps are spatially extended statistical processes that are used to test hypotheses about regionally specific effects in neuroimaging data. The implementation is not recursive (i.e. It uses the general lin-ear model (GLM) and random eld theory (RFT) to analyze and make inference about regional brain activities [4].
