PSYB51H3 Lecture Notes - Lecture 6: Saccade, Monocular Vision, Binocular Disparity
Document Summary
Our brain creates a 3d image from the projections. Our retinas are 2d projection surfaces with foveae. Requires eye (and head) movement for hd images. That requires 3d info to be recovered from flattened and distorted images. Rabbits have lateral eye; side of head so they can see 360 degrees around their heads. Humans have frontal eyes; 190 degrees from left to right, 110 of which is covered by both eyes. 6 muscles controlled by the cranial nerves (for 6 rotation movements) Are attached to each eye and are arranged in 3 pairs: These muscles are controlled by 3 cranial nerves. Eye movements are controlled in the cerebral cortex (ips, fef) and medial cortex. Superior colliculus: structure in midbrain that plays important role in initiating and guiding eye movements. The eye movements: smooth pursuit: voluntary eye movement where the eyes move smoothly to follow a moving object.
