Critical Thinking Questions

 

13Cocaine has two effects on synaptic transmission: it impairs reuptake of dopamine and it causes more dopamine to be released into the synaptic cleft. Would cocaine be classified as an agonist or antagonist? Why?
14Drugs such as lidocaine and novocaine act as Na+ channel blockers. In other words, they prevent sodium from moving across the neuronal membrane. Why would this particular effect make these drugs such effective local anesthetics?
15Examine Figure 3.14, illustrating the effects of sympathetic nervous system activation. How would all of these things play into the fight or flight response?
16Before the advent of modern imaging techniques, scientists and clinicians relied on autopsies of people who suffered brain injury with resultant change in behaviour to determine how different areas of the brain were affected. What are some of the limitations associated with this kind of approach?
17Which of the techniques discussed would be viable options for you to determine how activity in the reticular formation is related to sleep and wakefulness? Why?

Personal Application Questions

18Have you or someone you know ever been prescribed a psychotropic medication? If so, what side effects were associated with the treatment?
19You read about H. M.’s memory deficits following the bilateral removal of his hippocampus and amygdala. Have you encountered a character in a book, television program, or movie that suffered memory deficits? How was that character similar to and different from H. M.?
