Association fibers are bundles of axons within the brain that unite different parts of the same cerebral hemisphere.In human neuroanatomy, bundles of axons within the brain, called fibers, can be categorized by their function into association fibers, projection fibers, and commissural fibers.n human neuroanatomy, bundles of axons within the brain, called fibers, can be categorized by their function into association fibers, projection fibers, and commissural fibers.
Association and Commissural Fibers. Finally, regions of the cerebral cortex are tied together by bundles of white matter fibers. There are association bundles that connect one part of the cortex to another. These association fibers typically arise from layer III and terminate in layers I and II.ssociation and Commissural Fibers.
