Brain Tract Development - Commissural Fibers

3D depiction of developmental white matter fibers

b is an oblique view of the commissural fibers, where pink and green fibers in 13, 15, and 19 week brains are the corpus callosum and the middle cerebellar peduncle, respectively.

For anatomical guidance, the thalamus (yellow structure) and the ventricles (gray structure) are also shown.

Diffusion tensor imaging (DTI) A newly developed form of magnetic resonance imaging (MRI). Magnetic field variations of the MRI magnet are applied in at least six different directions generating a three dimensional shape of the diffusion pattern. This technique can be used in neural imaging of white matter due to the orientation of axon bundles and the associated water flow. (More? Magnetic Resonance Imaging)
