Control of Visually Guided Eye Movements
B. Subcortical Mechanisms of Visually Guided Saccadic Eye Movements
central subcortical structure involved in the generation of visually guided
saccadic eye movements is the superior colliculus. It resides on the roof
of the midbrain and is about the size of a pea. As in most visual structures,
the contralateral visual hemifield is laid out in an orderly fashion in
the structure as shown in Figure 4.
