Detailed explanation-1: -ASSOCIATION TRACTS: CONDUCT NERVE IMPULSES BETWEEN GYRI IN THE SAME HEMISPHERE. 2. COMMISSURAL TRACTS: CONDUCT NERVE IMPULSES FROM GYRI IN ONE CEREBRAL HEMISPHERE TO CORRESPONDING GYRI IN THE OTHER CEREBRAL HEMISPHERE ( CORPUS CALLOSUM, ANTERIOR COMMISSURE, AND POSTERIOR COMMISSURE.)

Detailed explanation-2: -The corpus callosum serves as the major connection between the hemispheres and conveys neural information from one hemisphere to the other. The corpus callosum is the largest of the side-to-side interconnections between the two hemispheres and, in general, connects analogous areas in the two hemispheres.

Detailed explanation-3: -Association tracts connect different regions within the same hemisphere of the brain. Long association fibers connect different lobes of a hemisphere to each other, whereas short association fibers connect different gyri within a single lobe.
