Why people use higher smoothing kernels for surface based measurements of brain?

Generally for tissue volumes(GM, WM and DBM) we use 8-12 FWHM for smoothing. But in some softwares recommend 15 mm for cortical thickness and 20-25 mm for all other indexes (gyrification, cortical...

Why tissue volume reductions are highlighted by DBM cannot be approximated by GM and WM findings of VBM of same sample?

My DBM results of 116 SZ and 116 NC show a greater coverage of both WM and GM areas. However WM findings of them are unable to confirm by VBM/WM findings. VBM/GM findings are looks OK in both...
