Mapping the white matter configuration of the spinal cord is of interest for understanding superspinal contribution to the generation of motion and coordination of muscles. Postmortem diffusion weighted MRI is a potent technique to investigate the microstructure of neuronal tissue. We have investigated fiber directions of the spinal cord in monkey using DT, Q-ball and PAS. Crossing fiber structures in the corticospinal tract was found using multi-fiber reconstruction techniques with good correlation to histological findings of terminating fibers.
