The Senses: How We Experience the World PowerPoint Presentation

Our senses do more than tell us when something smells sweet, or feels soft — they help us interpret our environment. This presentation will help you teach students how the brain processes our senses.

Your brain plays a vital role in your hearing and vision processes. When you hear, tiny cells in the inner ear transform vibrations in the air into every imaginable sound. When you see, the optic nerve carries light information to the visual processing center of the brain. When those processes are interrupted it can lead to vision or hearing loss, and in some cases even deafness or blindness. In these instances, however, there are many ways to recover some of what has been lost.

Click through the images in the slideshow to learn more about the causes of deafness and blindness and the research being done in these areas.
