Document Summary
Activity in these neurons go up a little before v4 does. they allow us to select a different stimulus in visual field frontal eye field plays a role in planning. & executing eye movement & without out eye movement posterior parietal cortex. Relaxed cilinary muscles = for focusing on distant target lens are thinner when muscles are relaxed. Perceptual organization in mt flashing blue circles example- we see blue dots moving side to side but its really not. Oculomotor cues: corollary discharge theory, correspondence problem object comes closer to eyes converge (they cross) eye muscles to keep fixated- this tells about depth if you"re eyes are very crossed its because the object is very close. 10 cm from eyes you"re eyes are very crossed. 1 meter from eyes not so crossed but still convergence. 4m or more from eyes, you"re eyes are converging because they are no longer crossed.
