Textbook Question
Chapter 38.2, Problem 3CC
WHAT IF? Two groups of individuals have CNS damage. In one group, the damage has resulted in a coma (a prolonged state of unconsciousness). In the other group, it has caused total paralysis (a loss of skeletal muscle function throughout the body). Relative to the position of the midbrain and pons, where is the likely site of damage in each group? Explain.

- Visit this site (http://openstaxcollege.org/l/neurolab) to see a virtual neurophysiology lab, and to observe electrophysiological processes in the nervous system, where scientists directly measure the electrical signals produced by neurons. Often, the action potentials occur so rapidly that watching a screen to see them occur is not helpful. A speaker is powered by the signals recorded from a neuron and it pops each time the neuron fires an action potential. These action potentials are firing so fast that it sounds like static on the radio. Electrophysiologists can recognize the patterns within that static to understand what is happening. Why is the leech model used for measuring the electrical activity of neurons instead of using humans?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_forwardCheck all that are true about cognition. A.

Neurons that process similar kinds of information are organized into what are called “neuron or neuronal pools.”Different ways of processing information occurs in these pools, depending on their function, and how they are organized. What are the two types of processing of information described below?___________________________________One neuron stimulates the next, which stimulates the next, and so on; the most clear cut example of this type of processing would be innate reflexes.___________________________________ This type of process can activate many pathways simultaneously, and is essential for high-level processes such as complex thinking and problem solving.arrow_forwardExplain the following mechanisms: 1. list three ways in which action potential can be initiated in neurons. 2.list the major classes of neurotransmitters and give examples of each . 3. list the functions of the hypothalamus and discuss how they relate to homeostatic control.arrow_forward
