Nerve tract

White matter tracts within a human brain, as visualized by MRI tractography

A nerve tract is a bundle of nerve fibers (axons) connecting nuclei of the central nervous system.[1][2][3] In the peripheral nervous system, this is known as a nerve fascicle, and has associated connective tissue. The main nerve tracts in the central nervous system are of three types: association fibers, commissural fibers, and projection fibers. A nerve tract may also be referred to as a commissure, decussation, or neural pathway.[4] A commissure connects the two cerebral hemispheres at the same levels, while a decussation connects at different levels (crosses obliquely).
