Comparison of VBM and DBM Methods by Study of Blind Men´s Brain Structures

Many studies have already demonstrated structural brain differences among different patient populations using the morphometric analysis techniques. Voxel-based morphometry (VBM) and deformation-based morphometry (DBM) are the two widely used methods. This paper mainly compared the difference of the two methods and analyzed the reason why many researches exist differences in the experimental results focused on the same disease. The blind men´s brain structures were analyzed using both VBM and DBM. The results based on the two methods exactly evaluated our analysis and provided evidence for the functional relevance of cross-modal plasticity studies.
