Tract
in the central nervous system, any one of several groups of closely placed nerve fibers having a common morphological structure and common functions. Tracts are divided by function into associative tracts, which unite various sections of the cerebral cortex in the same hemisphere; commisural tracts, which connect both hemispheres and ensure their cooperative activity; and projection tracts, which unite the cerebral cortex with lower brain formations and, through them, with the periphery.
