Topic:  Opening Vignette

Skill: Factual

Answer: a. injection of fetal nigrostriatal neurons into Mr. B.’s caudate nucleus and putamen

Rationale: The motor function of Mr. B was restored by an injection of fetal nigrostriatal neurons into Mr. B.’s caudate nucleus and putamen.

Topic:  Opening Vignette

Skill: Factual

Answer: a. dopamine; basal ganglia

Rationale: The symptoms of Parkinson’s disease relate to a lack of dopamine within the cells of the basal ganglia.

 

5.1-3.  Which of the following is true of the experimental ablation technique?

5.1-5.  Which of the following is a rationale for lesion studies?

1. The change in behavior that follows a particular brain lesion can give important clues about the function of that brain area.
2. Lesions are easily made within the brain.
3. Brain lesions are specific for fibers of passage.

Difficulty: 2

Question ID: 5.1-5

Page Ref: 132

Topic:  Evaluating the Behavioral Effects of Brain Damage

Skill: Conceptual

Answer: a. The change in behavior that follows a particular brain lesion can give important clues about the function of that brain area.

Rationale: The rationale for the ablation technique is that changes in behavior that follow a particular brain lesion can give important clues about the function of that brain area.
