Chapter 22, Problem 27RQ

A patient responds to the question What is your name? with a look of incomprehension. Which of the two major language areas is most likely affected and what is the name for that type of aphasia?

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?

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

Why do neurotransmitters have to be removed from the synapse?

Watch the video (http://openstaxcollege.org/l/2brains) titled The Man With Two Brains to see the neuroscientist Michael Gazzaniga introduce a patient he has worked with for years who has had his corpus callosum cut, separating his two cerebral hemispheres. A few tests are run to demonstrate how this manifests in tests of cerebral function. Unlike normal people, this patient can perform two independent tasks at the same time because the lines of communication between the right and left sides of his brain have been removed. Whereas a person with an intact corpus callosum cannot overcome the dominance of one hemisphere over the other, this patient can. If the left cerebral hemisphere is dominant in the majority of people, why would right-handedness be most common?

Explain what happens during synaptic integration.

A neuron responds to adequate stimulation with _______, a type of self-propagating signal.

Outline the components of the brain from the least specialized, oldest evolutionary level to the newest, most specialized level.

Julio D., who had recently retired, was enjoying an afternoon of playing golf when suddenly he experienced a severe headache and dizziness. These symptoms were quickly followed by numbness and partial paralysis on the tipper right side of his body, accompanied by an inability to speak. After being rushed to the emergency room, Julio was diagnosed as having suffered a stroke. Given the observed neurological impairment, what areas of his brain were affected?
