Document Summary

You see objects when they emit/reflect light that stimulates photoreceptors that transmit information to your brain. The brain will encode the information in a way that actually does not resemble what the actual object looks like (does so interns of the altered activity of neurons) One aspect of coding is which neurons are activated. Ex. ) activation of certain neurons indicate light whereas others indicate sound, touch, etc. Muller and his law of specific nerve energies applies in this situation. The eye and its connections to the brain. Light enters in the centre of the iris in an area called the pupil. Light is focused by the adjustable lens and the unadjustable cornea and then brought to the retina which contains visual receptors. Messages travel from the receptors to bipolar cells located closer to the centre of the eye which then send messages to ganglion cells whose axons join together to make up the optic nerve.
