Document Summary
Main ideas: each sensory neuron conveys a particular type of experience. How far you see depends on how far the light travels before it strikes the eyes; you do not send out sight rays. This was not known until arab philosopher ibn al-haythem demonstrated that light rays bounce off any object in all directions, but we see only those rays that strike the retina perpendicularly. You perceive something only when it alters your brain activity (ex. when you see a tree the perception is not in the tree, it is in your brain). You perceive an object when it emits or reflects energy that stimulates receptors that transmit information to your brain. Ren descartes- 17th century philosopher, believed that the brain"s representation of a stimulus resembled the stimulus; said that the nerves from the eye would project a pattern of impulses arranged like a picture, right side up (incorrect)
