Document Summary
Introduction our visual sense: humans are highly visually reliant animals as 1/3 of our brain"s function is to process visual info. If visual info is in conflict with info from another sense, we bias our trust towards vision: ex. In a movie theatre, we will hear audio from speakers but perceive it as coming from the actors. He cannot see but processing pathways are intact allowing him to recognize object locations, and coordinate with the motor cortex to avoid them while moving. The eye: cornea the curved structure through which light first passes through transparent window at the front of the eye, pupil black dot through which light passes through second. Iris coloured part of the eye that controls the size of the pupil: has muscles that are controlled by the brain. If less light is reaching the retina, muscles dilate the pupil into a larger opening. If the object is close, the lens gets fatter or rounder.
