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.
These association neurons are found throughout the central nervous system. They are much more numerous than motor neurons; the ratio between the two types of cells is 30:1. The main function of the association neurons in the spinal cord is that of inhibitory control. They also interconnect other cells with one another.
