NROC64H3 Lecture Notes - Lecture 8: Medial Rectus Muscle, Smooth Pursuit, Stereopsis
Document Summary
Saccades and fixations used to target and pinpoint eye only moves during very brief movements most of time you are fixating; thats what gives jerky appearance of eye movement traces. Slide 3: face picture; when forming little knots; eye is being relatively stable eye is not totally stable; not moving at all monkeys make eye movements faster than humans b/c their eyes are smaller. Saccades in their size: amplitude are under voluntary control;; velocity itself is not under voluntary movement little peak represents velocity in velocity plot. Vestibulo-ocular reflex driven by vestibular system; can be translation or rotation that drives eye movements goal: to keep eyes stable. Optokinetic nystagmus: sawtooth movements looks similar to prev eye movements quick phases; due to visual system quick movements; optic systems try to follow features of outside world purpose is to keep line of sight straight in space.
