21Thalamic RadiationCorticothalamic fibers project within internal capsule from cerebral cortex to thalamus.Thalamocortical fibers project within internal capsule from thalamus to cerebral cortex.
22Corticopontine Projections Corticopontine fibers projects to pontine nuclei in the pons.Pontine nuclei project to cerebrellum.
23Corticobulbar Projections Part of pyramidal tracts.Originate mostly in motor cortex.Project to cranial nerve nuclei in brainstem.
24Corticospinal Projections Part of pyramidal tracts.Originate mostly in motor cortex.Project to cell groups throughout all parts of spinal cord.
25Corticoreticular Projections Originate in motor and somatosensory cortex.Project to brainstem reticular formations.
26Optic Radiation = Geniculocalcarine tract. Originates in lateral geniculate body.Runs in lateral direction in the internal capsule.Makes a sharp bend (= Meyer’s loop).Runs in caudal direction toward calcarine fissure in occipital lobe.
27FornixMajor projection system between the hippocampus in temporal lobe and the diencephalon.
