FIGURE 13.57
The important sites for the generation of a conjugate horizontal saccade in both eyes. Excitatory
inputs are shown with , and inhibitory inputs are shown with . Consistent with current knowledge, the left
and right structures of the neural circuit model are maintained. Since interest is in goal-directed visual saccades,
the cortex has not been partitioned into the frontal eye field and posterior eye field (striate, prestriate, and inferior
parietal cortices).
