PSYB51H3 Lecture Notes - Lecture 6: Cerebral Cortex, Retina, Vergence
Document Summary
The eyes are still moving a little bit, little eye movements that refresh the retina so that we don"t have too much adaptation. Two types of eye muscles: rectus muscles: inferior rectus, superior, lateral and medial. Oblique eye movements: if have legions in these areas might be selective~ only horizontal eye movements and not vertical eye movements. Fixating on pen experiment- following it with your eyes. A lot of eye problems can not do this - neurological test. The older we get, the more problems we have with this. Smooth pursuit is to keep stuff stable on our fovea- we want stuff to be stable on our retina . Fixate on the pen- on the retina it will move around because it is following it the finger behind stays stable. Vision is interpreted different whether you believe you are making an eye movement or not: saccades: reduce travel time. To move the fovea to objects of interests.
