Conceptualize a problem of REM sleep.

9. Vertex shape waves often appear toward the end of which of the following sleep stages? A. Stage N1 non-REM sleep B. Stage N2 non-REM sleep C. Stage N3 non-REM sleep D. REM sleep

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?

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?

A presynaptic neuron in the cerebrum transmits information to hundreds of other neurons. This process is an example of (a) convergence (b) divergence (c) temporal summation (d) spatial summation (e) a graded potential

Watch this video (http://openstaxcollege.org/l/basalnuclei1) to learn about the basal nuclei (also known as the basal ganglia), which have two pathways that process information within the cerebrum. As shown in this video, the direct pathway is the shorter pathway through the system that results in increased activity in the cerebral cortex and increased motor activity. The direct pathway is described as resulting in disinhibition of the thalamus. What does disinhibition mean? What are the two neurons doing individually to cause this?

Which of the following tests cerebellar function related to gait? toe-to-finger station lah-kah-pah finger-to-nose

Watch this video (http://openstaxcollege.org/l/basalnuclei2) to learn about the basal nuclei (also known as the basal ganglia), which have two pathways that process information within the cerebrum. As shown in this video, the indirect pathway is the longer pathway through the system that results in decreased activity in the cerebral cortex, and therefore less motor activity. The indirect pathway has an extra couple of connections in it, including disinhibition of the subthalamic nucleus. What is the end result on the thalamus, and therefore on movement initiated by the cerebral cortex?

The part of the brain that is responsible for coordination during movement is the ______. a. limbic system b. thalamus c. cerebellum d. parietal lobe

Brodmanns areas map different regions of the ________ to particular functions. cerebellum cerebral cortex basal forebrain corpus callosum
