◉ The emotional and declarative aspects of a memory for a stressful
event. Answer: are the result of independent activity in the amygdala and
hippocampus, respectively.
◉ Post-traumatic stress disorder (PTSD) might someday be prevented
by. Answer: the injection of propanolol, which blocks glucocorticoids.
◉ Short-term habituation in Aplysia, lasting minutes to several hours,
most likely results from. Answer: the temporary depletion of available
neurotransmitter in the presynaptic sensory neuron.
◉ Repeated exposure to habituation or sensitization changes the number
of. Answer: axon terminals on sensory neurons.
◉ It appears that circuits connecting the amygdala, hippocampus, and
medial prefrontal cortex participate in matching correct responses to
their contexts following _______ training.. Answer: Extinction
,◉ Important attentional aspects of short-term memory require activation
in the. Answer: dorsolateral prefrontal cortex and the anterior cingulate
cortex.
◉ Your great uncle recently had a stroke, and there have been some
subtle differences in his behavior. For example, you were playing
checkers, and he was doing fine. But when your checker was "kinged"
and could therefore move according to a different set of rules, he didn't
seem to be able to adjust. When you asked him if he realized what the
rules said, he did, but he continued to play as if he didn't. Considering
what you learned about brain areas and memory, what part of his brain
would you suspect has damage?. Answer: prefrontal cortex
◉ James constantly asks his friend Rob to tell him what the professor
just said in lecture, because James has much more trouble remembering
verbal information long enough to write it down in his notes. It is likely
that James. Answer: is more likely than Rob to use simple repetition to
remember verbal material.
◉ Thiamine deficiencies characteristic of chronic alcoholics may
produce. Answer: severe anterograde and retrograde amnesia.
◉ While naming animals or tools, participants showed activation in.
Answer: separate areas including the occipital, frontal, and temporal
lobes.
, ◉ Samantha's grandfather has been diagnosed with Parkinson's disease.
Samantha knows that Parkinson's disease affects the basal ganglia, so
she is able to tell her grandfather that he is likely to experience. Answer:
problems with procedural memories, but not declarative memories.
◉ When responses to environmental stimuli are actually increased
following exposure to a strong stimulus, which of the following
processes has occurred?. Answer: Sensitization
◉ Eyeblink conditioning in human participants. Answer: is impaired in
participants with cerebellar damage.
◉ In sensitization in Aplysia, what processes account for the stronger
than normal responses of gill motor neurons?. Answer: extended action
potentials in siphon sensory neurons, which result in the release of
greater than normal amounts of neurotransmitter at synapses with gill
motor neurons.
◉ Long-term depression (LTD) reflects _________ in Purkinje cells..
Answer: decreases in EPSPs
◉ Longer-term habituation in Aplysia, lasting up to three weeks, most
likely results from. Answer: changes in NMDA glutamate receptors
