Keywords fMRI; spatial smoothing; group analysis
Description fMRI images are pre-processed before the activation can be statistically detected. One of the pre-processing steps is spatial smoothing. The aim of this work is to discover the impact of spatial filtering with the Gaussian kernel and various FWHM sizes on group results.
