Textbook Question
Chapter 49.4, Problem 3CC
WHAT IF? Ø Suppose that a person with damage to the hippocampus is unable to acquire new long-term memories. Why might the acquisition of short-term memories also be impaired?

QUESTION 22
Which one is not the best way to describe necessary "threshold" as "sensitivity" declines with age?
Individuals with lower sensitivity also have a lower threshold or tolerance for stimulation.
O
As sensitivity goes down, the threshold must be higher to compensate.
Individuals with a low-sensitivity, need more stimulation than people with high-sensitivity.
none of the above
QUESTION 23
WHAT IF? Suppose you examine two groups of individuals with CNS damage. In one group, the damage hasresulted in a coma (a prolonged state of unconsciousness). In the other group, it has caused paralysis (a loss ofskeletal muscle function throughout the body). Relativeto the position of the midbrain and pons, where is thelikely site of damage in each group? Explain

- 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?arrow_forwardHi please helparrow_forwardWhich of the following statements about the hippocampus is NOT true?

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 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
