1. What YOU thinkbiopsychology is?2. Where does it fitinto psychology?3.Where does it fit into science?4.Whateffects can a neurotransmitter have on the recipient cell?5.Shoulddrugs that improve cognitive functions such as attention be available toeveryone or only to people with significantly impaired function, such asattention deficit hyperactivity disorder (ADHD)?6.What commonalities exist between alladdictive drugs in terms of their effects on the brain?7.If incoming serotonin axons were destroyed,LSD would still have its full effects. However, if incoming dopamine axons weredestroyed, amphetamine and cocaine would lose their effects. Explain thedifference.8.Suppose axon A enters a ganglion (a clusterof neurons) and axon B leaves on the other side. An experimenter who stimulatesA can shortly thereafter record an impulse traveling down B. We want to knowwhether B is just an extension of axon A or whether A formed an excitatorysynapse on some neuron in the ganglion, whose axon is axon B. How could anexperimenter determine the answer? You should be able to think of more than onegood method. Presume that the anatomy within the ganglion is so complex thatyou cannot simply trace the course of an axon through it.9. Being nervous interferes with sexual arousal. Explain why,with reference to the sympathetic and parasympathetic nervous systems.
10. Howis the sympathetic branch of the autonomic nervous system similar or differentfrom the parasympathetic branch?
11. What is “binding” and why is it important?
12. Why is the”dorsal-ventral” axis not synonymous with the “posterior-anterior” axis in thewhole human nervous system?13.The majority of infant crib toys are produced in pastel shades such as lightblue or pink. Based on research on the visual abilities of newborns, have theclass discuss the colors and designs for toys that would stimulate the infantvisual system.14. Beyond the problems associated with reading, research has demonstrated thatindividuals with dyslexia have problems with basic sensory processing. Forexample, individuals with dyslexia have a difficult time identifying when agrouping of dots is moving relative to the background, especially as thecontrast between the dots and the background decreases. This implies that oneof the visual pathways may be abnormal in individuals with dyslexia. Whichpathway would you suspect and what parts of the brain might you want toinvestigate to support your hypothesis?Developmental Perspectives onthe Functions of Sleep Infants sleep considerably more than adult humans. Theyalso have sleep patterns that are qualitatively different from adults. Havestudents research the sleep patterns of infants and discuss how thesedevelopmental differences support the Restoration and Energy Conservationtheories of sleep. 16 Why would it be harder todeprive someone of just NREM sleep than just REM sleep? 17. What is therelationship between sleep and memory?18. Many children withautism have sleeping problems and are given melatonin. What effect is thislikely to have and when would be the best time to give the melatonin?19.Unlike adults, infantsalternate between short waking periods and short naps. What can we infer abouttheir neurotransmitters?
