  • Description: <jats:p xml:lang="en">Functional&#x0D; magnetic resonance imaging is a technique with a primary and dominant effect in&#x0D; the investigation of the cognitive functions of the brain since it has a&#x0D; complex structure. In this study, data obtained from single subject was&#x0D; examined. First statistical parametric mapping results were obtained after&#x0D; applying the standard preprocessing steps with including smoothness. Spatial&#x0D; smoothing was performed using a 3 mm Gaussian kernel which is twice of the&#x0D; voxel size. Second, statistical parametric mapping results were obtained with&#x0D; applying standard preprocessing steps without smoothing. The effects of these&#x0D; two applications on the mapping results were compared for selected slices and&#x0D; locations in terms of statistical and pattern.</jats:p>
