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?
Watch this video (http://openstaxcollege.org/l/whitematter) to learn about the white matter in the cerebrum that develops during childhood and adolescence. This is a composite of MRI images taken of the brains of people from 5 years of age through 20 years of age, demonstrating how the cerebrum changes. As the color changes to blue, the ratio of gray matter to white matter changes. The caption for the video describes it as less gray matter, which is another way of saying more white matter. If the brain does not finish developing until approximately 20 years of age, can teenagers be held responsible for behaving badly?
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?
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?
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?
Which white matter structure carries information from the cerebral cortex to the cerebellum? cerebral peduncle superior cerebellar peduncle middle cerebellar peduncle inferior cerebellar peduncle
Watch this video (http://openstaxcollege.org/l/lumbarpuncture) that describes the procedure known as the lumbar puncture, a medical procedure used to sample the CSF. Because of the anatomy of the CNS, it is a relative safe location to insert a needle. Why is the lumbar puncture performed in the lower lumbar area of the vertebral column?
Compared with the nearest evolutionary relative, the chimpanzee, the human has a brain that is huge. At a point in the past, a common ancestor gave rise to the two species of humans and chimpanzees. That evolutionary history is long and is still an area of intense study. But something happened to increase the size of the human brain relative to the chimpanzee. Read this article (http://openstaxcollege.org/l/hugebrain) in which the author explores the current understanding of why this happened. According to one hypothesis about the expansion of brain size, what tissue might have been sacrificed so energy was available to grow our larger brain? Based on what you know about that tissue and nervous tissue, why would there be a trade-off between them in terms of energy use?

Usuing MRI's and PET scans, reseachers are studying the functioning on the brain. Comment possible positive and negative ramifications this could have on developing more effective pshotropic medication to control the mind?
Some survivors of disastrous events have post-traumaticstress disorder (PTSD). Symptoms include nightmaresabout the experience and suddenly feeling as if the eventis recurring. Brain-imaging studies of people with PTSDshowed that their hippocampus was shrunken and theiramygdala unusually active. Given these changes, whatother brain functions might be disrupted in PTSD?
