Document Summary
Store information in terms of responses by neurons: which neurons respond, amount of response and timing. Impulses in one neuron indicates light and impulses in another neuron indicate sound. Nerves impulses do not arrive in patterns that look like the original scene. The eye and its connections to the brain: Pupil: where light enters the eye through an opening in the center of the iris. Retina: rear surface of the eye lined with visual receptors. Located closer to the center of the eye. Messages go from retina to receptors at the back of the eye to bipolar cells. Located even closer to the center of the eye. Axons of these cells travel back to the brain. Amacrine cells get information from bipolar cells and send it to other bipolar, amarcrine and ganglion cells. Consequence is that light passes through ganglion and bipolar cells to the receptors but these cells are transparent and pass through cells without distortion.
