3 Chapter 2: Neuroscience and Behavior You’re on, Neuron! It’s all in your head. That Smarts! The Systems Potpourri

4 1. Branching fibers extending out from the cell body to receive information from other neurons are called: A) axons. B) glial cells. C) dendrites. D) axon terminals. 55

5 2. ___ wrap(s) many axons, insulating them and speeding their impulses. A) Sodium ions B) Myelin C) Glial cells D) Potassium ions 55

6 3. The brief electrical impulse transmitted along the axon is called the: A) action potential. B) stimulus threshold. C) electrical cascade. D) sodium pump. 55

7 4. After neurotransmitters are released into the synapse, many are reabsorbed through a process called: A) synaptic transmission. B) reuptake. C) all-or-none. D) reabsorption. 57

8 5.The neurotransmitter ___ is important in memory. Depletion of it is found in those with Alzheimer’s A) dopamine B) GABA C) serotonin D) acetylcholine 58

9 6. The device called a(n) ___ provides moment-by-moment images of the brain’s changing activity and is noninvasive. A) EEG B) PET scan C) MRI D) fMRI 69

10 7. The ___ receives information from all the senses except smell. A) hippocampus B) amygdala C) thalamus D) angular gyrus 68

13 10. Auditory information is received and processed in the: A) somatosensory cortex. B) temporal lobe. C) parietal lobe. D) frontal lobe. 76

14 11. An impaired use of language due to a brain lesion is known as: A) tomography. B) aphasia. C) plasticity. D) phrenology. 80

15 12. The ability of one part of the brain to take over the function of another in case of injury is called: A) plasticity. B) neurogenesis. C) brain reintegration. D) neural net reformation. 82

16 13. After Sam’s stroke, he had difficulty speaking, but could understand what others were saying to him. He likely had damage to: A) Wernicke’s Area. B) Broca’s Area. C) his Thalamus. D) his parietal lobe. 81

17 14. After a sky-diving accident, Laurie was unable to make sense of other people’s speech. It is likely that her cortex was damaged in: A) the sensory area. B) Broca’s area. C) the angular gyrus. D) Wernicke’s area. 81

18 15. In a recent car accident, Justin sustained damage to his right cerebral hemisphere. This injury is most likely to reduce his ability to: A) tell an angry face from a happy one. B) solve arithmetic problems. C) speak clearly. D) process information quickly. 80

19 16. In order for you to experience the pain of being stuck with a pin, ___ must first relay messages from your ankle to your central nervous system. A) the limbic system B) interneurons C) sensory neurons D) the reticular formation 62

20 17. When you’re stressed and your heart races, perspiration increases and pupils dilate, the ___ is activated. A) somatic nervous system B) parasympathetic branch C) sympathetic branch D) spinal reflex 62

21 18. James touched a hot stove. His hand immediately recoiled before he knew it was hot. The sequence of this reflex is: A) sensory neurons, interneurons, motor neurons. B) sensory neurons, motor neurons, interneurons. C) interneurons, sensory neurons, motor neurons. D) interneurons, motor neurons, sensory neurons. 63
