Chapter 13, Problem 3RQ

When eating food, what anatomical and functional divisions of the nervous system are involved in the perceptual experience?

Watch this video (http://openstaxcollege.org/l/3Dmovies) to learn about the side effects of 3-D movies. As discussed in this video, movies that are shot in 3-D can cause motion sickness, which elicits the autonomic symptoms of nausea and sweating. The disconnection between the perceived motion on the screen and the lack of any change in equilibrium stimulates these symptoms. Why do you think sitting close to the screen or right in the middle of the theater makes motion sickness during a 3-D movie worse?

What is a synapse? Explain the difference between an excitatory and an inhibitory synapse.
