21 Thalamic RadiationCorticothalamic fibers project within internal capsule from cerebral cortex to thalamus.Thalamocortical fibers project within internal capsule from thalamus to cerebral cortex.
22 Corticopontine Projections Corticopontine fibers projects to pontine nuclei in the pons.Pontine nuclei project to cerebrellum.
23 Corticobulbar Projections Part of pyramidal tracts.Originate mostly in motor cortex.Project to cranial nerve nuclei in brainstem.
24 Corticospinal Projections Part of pyramidal tracts.Originate mostly in motor cortex.Project to cell groups throughout all parts of spinal cord.
25 Corticoreticular Projections Originate in motor and somatosensory cortex.Project to brainstem reticular formations.
26 Optic 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.
27 FornixMajor projection system between the hippocampus in temporal lobe and the diencephalon.
