3.Where does it fit into science?
effects can a neurotransmitter have on the recipient cell?
drugs that improve cognitive functions such as attention be available to
everyone or only to people with significantly impaired function, such as
attention deficit hyperactivity disorder (ADHD)?
6.What commonalities exist between all
addictive 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 were
destroyed, amphetamine and cocaine would lose their effects. Explain the
8.Suppose axon A enters a ganglion (a cluster
of neurons) and axon B leaves on the other side. An experimenter who stimulates
A can shortly thereafter record an impulse traveling down B. We want to know
whether B is just an extension of axon A or whether A formed an excitatory
synapse on some neuron in the ganglion, whose axon is axon B. How could an
experimenter determine the answer? You should be able to think of more than one
good method. Presume that the anatomy within the ganglion is so complex that
you 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.
is the sympathetic branch of the autonomic nervous system similar or different
from 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 the
whole human nervous system?
13.The majority of infant crib toys are produced in pastel shades such as light
blue or pink. Based on research on the visual abilities of newborns, have the
class discuss the colors and designs for toys that would stimulate the infant
14. Beyond the problems associated with reading, research has demonstrated that
individuals with dyslexia have problems with basic sensory processing. For
example, individuals with dyslexia have a difficult time identifying when a
grouping of dots is moving relative to the background, especially as the
contrast between the dots and the background decreases. This implies that one
of the visual pathways may be abnormal in individuals with dyslexia. Which
pathway would you suspect and what parts of the brain might you want to
investigate to support your hypothesis?
Developmental Perspectives on
the Functions of Sleep Infants sleep considerably more than adult humans. They
also have sleep patterns that are qualitatively different from adults. Have
students research the sleep patterns of infants and discuss how these
developmental differences support the Restoration and Energy Conservation
theories of sleep.
16 Why would it be harder to
deprive someone of just NREM sleep than just REM sleep?
17. What is the
relationship between sleep and memory?
18. Many children with
autism have sleeping problems and are given melatonin. What effect is this
likely to have and when would be the best time to give the melatonin?
19.Unlike adults, infants
alternate between short waking periods and short naps. What can we infer about
