We present a neuroanatomical comparison with stereotaxic precision correlating modern diffusion tensor imaging (DTI), MRI data and classical neuroanatomical textbooks. The neuroatlas compiled by J. and A. Dejerine deserves emphasis for its role of a bridge between precise classical neuroanatomy techniques with modern neuroimaging methods. We present its utility in identifying major white matter tracts of the brain in concert with DTI in the horizontal-plane axis to elucidate axonal directionality. The axonal directionality of DTI is necessary for understanding white matter connectivity in the brain. Many DTI studies publish findings in selective regions of the brain, and our study is mainly devoted to comparing our images with data from Dejerine for the entire brain.
