Brain Tract Development - projection fibers

3D depiction of developmental white matter fibers

A lateral view of projection fibers, where red and purple fibers in 13, 15, and 19 week brains are the cerebral peduncle and the inferior cerebellar peduncle, respectively.

d is a lateral view of association tracts, in which blue fibers in brains of 13 and 15 weeks are the external capsule, and green and red fibers in a brain of 19 weeks are the inferior longitudinal fasciculus/inferior fronto-occipital peduncle and uncinate fasciculus, 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)
