  2. #DIBSBYNEXTILLO DAILY INFORMATION BULLETIN SERVICE WHITE MATTER TRACTS There are three different kinds of tracts (bundles of axons) that connect one part of the brain to another within the white matter: Projection tracts/Projection fibers Commissural tracts/Commissural fibers Association tracts/Association fibers NEXTILLO.COM

  3. PROJECTION FIBERS Projection fibers are afferent and efferent tracts that interconnect areas of the cortex with the brainstem, deep nuclei and cerebellum, and spinal cord. Of these, the main ones identifiable on DTI include the corticospinal, corticobulbar, corticopontine, and geniculocalcarine tracts (optic radiations). The thalamus is known to have reciprocal connections . NEXTILLO.COM

  4. COMMISURAL TRACTS Commissural fibers are the white matter tracts connecting corresponding homologous regions between the 2 hemispheres. The main structures discussed are the corpus callosum and anterior commissure. The main function of the corpus callosum is interhemispheric sensorimotor and auditory connectivity. The anterior commissure is a small compact bundle of fibers between the anterior and posterior columns of the fornix. NEXTILLO.COM

  5. ASSOCIATION FIBERS Association fibers unite different cortical areas within the same hemisphere and can be short or long. Short association fibers connect areas within the same lobe and include subcortical U fibers, which connect adjacent gyri. Long association fibers include the SLF, inferior longitudinal fasciculus, middle longitudinal fasciculus (MLF), uncinate fasciculus, superior fronto-occipital fasciculus, and inferior fronto-occipital fasciculus.
