Effects of frontal eye field and superior colliculus ablations on eye movements.
Two parallel neural pathways are primarily responsible for the control of saccadic eye movements--one mediated through the frontal eye fields and the other through the superior colliculus. When both pathways are disrupted, control of saccadic eye movements is lost. Disruption of either pathway alone produces only subtle deficits.
