-FIXME+
  
 +==== Supranuclear Pathways ====
 +  * Frontal Eye Fields
 +    * Saccades originate here on the contralateral side of the direction of the saccade
 +    * Left Frontal eye field generates signal to right pons for horizontal saccades and 
 +  * Parietal Occipital Temporal Region generates pursuit movements and uses the same downstream pathways
 +====Nuclear Centers====
 +  * Horizontal eye movement- Pons
 +    * Oculomotor Nucleus
 +    * Abducens Nucleus
 +  * Vertical eye movements- Midbrain at the Thalamo-mesocenphalic junction  
 +====Internuclear Pathways====
 +  * PPRF- parapontine reticular formation 
 +    * near the 6th nerve nucleus
 +  * MLF- coordinates horizontal gaze nuclei 
 +    * Connects the 6th nerve nucleus to the 3rd nerve nucleus 
 +====Infranuclear Pathways====
 +  * Nerve axons to synapse then muscle contraction
 +==== Diagram of Horizontal Gaze Pathways ====
