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.
The first type of fiber we will look at is the type I, or slow twitch fibers. These fibers are slow to contract (hence, slow twitch), and can sustain muscular contractions for an extended period of time. This factor makes them ideal for endurance type of events where one is exercising for long durations.
