Coronal section of the brain (thalamus level): White matter structures (Latin)

The largest collection of white matter fibers in the human brain is the corpus callosum. The truncus corporis callosi is seen on this coronal section inferior to the gyrus cinguli. Further below at the center of the illustration is a cross section of the corpus fornici, running between the two thalami. Lateral to each thalamus is a large bundle of white matter called the capsula interna, separating the thalamus from the corpus striatum. Between the putamen and the claustrum is a smaller bundle of white matter called the capsula externa. Lastly, the most lateral bundle is the capsula extrema, found between the claustrum and the insula.
