Brain Tract Development - Limbic Tracts

3D depiction of developmental white matter fibres. The medial limbic system (circuit) is also called the Papez circuit. Named after James Papez in 1937 proposed a connection between the hypothalamus to the limbic lobe involved in control of emotional expression. Components of the limbic system communicate by the cingulum, white matter fibers projecting from the cingulate gyrus to the entorhinal cortex.


A lateral view of limbic tracts where pink fibers in 13, 15, and 19 week brains are the fornix and stria terminalis and purple fibers in the 19 week brains indicate the cingulum bundle.

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)
