Huntington's disease is characterized by a loss of normal inhibition mediated by the basal nuclei. Predict the symptoms you are likely to see with this disease.

Mark the following statements about the cerebral cortex as true or false. If a statement is false, correct it to make a true statement.

b. The cerebral cortex is composed of white matter.

Mark the following statements about the cerebral cortex as true or false. If a statement is false, correct it to make a true statement.

c. The primary visual cortex is located in the occipital lobe.

Mark the following statements about the cerebral cortex as true or false. If a statement is false, correct it to make a true statement.

d. The prefrontal cortex is located in the frontal lobe and is concerned with movement.

The central sulcus separates the:

a. parietal and temporal lobes.

b. parietal and occipital lobes.

c. frontal and temporal lobes.

d. frontal and parietal lobes.

How could you tell the difference between an injury that damaged the cerebellum and one that damaged the basal nuclei?

Why do injuries to the hippocampus interfere with the formation of new declarative memories but do not impact memories already encoded in long-term memory? Why do such injuries not affect the formation of nondeclarative memories?

Ms. Norris is brought to the emergency department with injuries to the posterior of her head resulting from a motor vehicle accident. Which lobes of the cerebrum likely sustained injuries? Predict the main signs and symptoms you will see resulting from the injury to these cerebral lobes.

On further examination, Ms. Norris is shown to be in a state of unarousable unconsciousness, or coma. Which area or system of the brain is likely damaged? Explain.
