Summary Introduction

To review: How the vertebral brain processes sensory information obtained from vision differently than the sensory information from hearing and olfaction.

Introduction:

The mechanism in which the information is transmitted in the form of neurotransmitter in case of vision is when the light enters the cornea; it passes through pupil and iris. Then the light rays reach the vitreous humor and moves to the retina. The retina transmits the signals to the optic nerve, which further reaches the optic tract, optic radiation, and the cortex. After this, the signals reach to the occipital cortex and are interpreted as an image by the visual cortex.
