        frontal eye field area 8 middle frontal gyrus
        
        function: generates contralateral conjugate gaze movements
        
        lesion: the contralateral field predominates for few hours: looks at the lesion. When contralateral movements toward the midline are possible again: gaze-paretic nystagm, rapid compontent beat away from the lesion
        
        posterior hemispheric cortex - occipital lesion is accompanied by hemianopsia. Saccadic ocular persuit
      - paramedian pontine reticular formation PPRF
        
        function: relays information from cortical centers to ipsilateral n. VI. nucleus (m. rectus lat) + contralateral n. III (m. rectus med.)
        
        lesion: permanent gaze palsy to the side of the lesion, BUT: do not effect vestibulo-ocular connections, can be overcome with vestibular nystagmus
      - abducens nucleus
        
        function: n VI (ipsilateral m. rectus lat) + interneurons towards MLF (medial longitudinal fasciculus) and n. III - contralateral m. rectus med.
        
        lesion: initially very similar to lesion of PPRF, but cannot be overcome voluntarily of through any reflex
