SPM Full Form in Medical term is Statistical Parametric Mapping. It is a numerical technique for measuring variation in brain activity captured during functional neuroimaging experiments, which is a certain type of brain scanning. This includes an assessment of brain activity.
Depending on the imaging technique, including PET and MRI, the measurement technique varies. In this technique, a scanner maps an area that is represented as voxels, each of which represents a certain amount of activity in three-dimensional space. The appropriate tone size varies depending on the technology.
Researchers testify to the brain’s activity, considering certain mental processes. Visuals from the scanner may be pre-processed to correct sampling errors or eliminate noise. To account for head movement during the scan, the images are typically adjusted so that the voxels in each image are at approximately the same location in the brain. Also called motion correction or realignment, this technique consists of images that can be smoothed to make the data less noisy.
