autoradiographic experiments showed that the incertofugal fiber systems reach ipsilaterally to the thalamus ( lateral dorsal , central lateral , ventral lateral geniculate , parafascicular , subparafascicular and reuniens nuclei , and posterior nuclear complex ) , to the hypothalamus ( dorsal , lateral and posterior hypothalamic areas ) , to the tectum ( medial pretectal area , deep pretectal and pretectal nuclei , superior colliculus and periaqueductal gray ) and to the midbrain tegmentum , pons and medulla oblongata ( subcuneiform , cuneiform and red nuclei , nuclei of the posterior commissure and darkschewitsch , interstitial nucleus of cajal , pedunculopontine tegmental nucleus , oral and caudal pontine reticular nuclei , nucleus raphe magnus , gigantocellular reticular nucleus , pontine gray and inferior olivary complex ) .
