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?arrow_forward
- 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?arrow_forwardWatch this video (http://openstaxcollege.org/l/neuroexam) that provides a demonstration of the neurological exam—a series of tests that can be performed rapidly when a patient is initially brought into an emergency department. The exam can be repeated on a regular basis to keep a record of how and if neurological function changes over time. In what order were the sections of the neurological exam tested in this video, and which section seemed to be left out?arrow_forwardWatch 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?arrow_forward
- Match the terms with their descriptions. ____ thalamus a. coordinates motor activity ____ dopamine b. connects the hemispheres ____ limbic system c. protects brain and spinal cord from some toxins ____ corpus callosum d. one type of neurotransmitter ____ cerebral cortex e. support team for neurons ____ cerebellum f. wrap brain and spinal cord ____ neuroglia g. roles in emotion and memory ____ ganglion h. most complex integration ____ blood-brain barrier i. cluster of neuron cell bodies ____ meninges j. regulates sleep-wake cyclearrow_forwardThe part of the brain that is responsible for coordination during movement is the ______. a. limbic system b. thalamus c. cerebellum d. parietal lobearrow_forwardWatch 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?arrow_forward

This leads to the discovery of a hereditary condition that affects the brain and spinal cord. The electromyography and MRI tests indicated deficiencies in the spinal cord and cerebellum, both of which are responsible for controlling coordinated movements. To what functional division of the nervous system would these structures belong?arrow_forwardPhineas Gage was a 19th century railroad worker who survived an accident that drove a large iron rod through his head.
