PSYB51H3 Lecture Notes - Lecture 6: Projective Geometry, Correspondence Problem, Binocular Summation
Document Summary
6 muscles are attached to each eye and are arranged in three pairs, which are controlled by an extensive network of structures in the brain: inferior/superior/lateral/medial rectus, inferior/superior oblique. Superior colliculus: structure in the midbrain that plays an important role in initiating and guiding eye movements. When stimulated with electrical signals, eye movements can be observed. vestibular eye movements: when the eyes move to compensate for head and body movement while maintaining fixation on a particular target. optokinetic nystagmus: eyes involuntarily track a continuously moving object: fixational eye movements, microsaccades. Function of smooth pursuit eye movements: to keep the object of interest stable and on the fovea. Why do we perceive the pencil to be in motion in the first case, but perceive the dot to be stationary in the second case: because in one case there is an eye movement. Similar effects can be observed with saccadic eye movements.
