<P> The projection fibers consist of efferent and afferent fibers uniting the cortex with the lower parts of the brain and with the spinal cord . In human neuroanatomy , bundles of axons ( nerve fibres ) called tracts , within the brain , can be categorized by their function into association fibers , projection fibers , and commissural fibers . </P>
