ans projection fibres.

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 fibers) called tracts, within the brain, can be categorized by their function into association fibers, projection fibers, and commissural fibers.

In the neocortex, projection neurons are excitatory neurons that send axons to distant brain targets.Considering the six histologically-distinct layers of the neocortex, associative projection neurons extend axons within one cortical hemisphere; commissural projection neurons extend axons across the midline to the contralateral hemisphere; and corticofugal projection neurons extend axons away from cortex.

Numerous fibers arising within the thalamus, and passing through its stalks to the different parts of the cortex;are afferent projection fibres.
