Document Summary
On the retina, the image of the professor is moving and the image of the blackboard is steady. On the retina, the image of the professor is steady and the image of the blackboard is moving. The subjective experience is that the professor is moving and the blackboard is steady. On the retina, the image of the professor and the image of the blackboard are moving. The subjective experience is that the professor and the blackboard are steady. Retinal image is the opposite of the subjective experience. Comparator separates out movement on the back of the eye due to eye movement from movement on the back of the eye due to object movement. Cds corollary discharge signal copy of the motor signal instruction. Corollary discharge theory: any time you make an eye movement, a copy of that muscle instruction is sent to the comparator, which filters out any retinal image change that corresponds exactly to that eye movement instruction.
