Statistical analysis of morphological differences between brains

Recent study in neuroscience has observed evidence that the anatomic structures in human brains might have certain connection with the functioning. This triggers the interest in morphological study of cortical surfaces and in comparison of different ethnic groups. This article compares the MRI brain datasets of 10 Chinese and 10 Caucasians. A statistical analysis was applied to the white matter volumes in these datasets and evaluate the dissimilarities between the two groups using various intuitive measures. This analysis has revealed systematic morphological differences between the two ethnic groups.
