Learning and Amnesia

• Practice questions

2
What we remember about an episode that permits us
to retrieve it later

• a. are a few striking details.
• b. are the events and the context in which they
  occur.
• c. is the information that is inconsistent with
  what we already know.
• d. is the information about it that we rehearse.

3
The most important input to the hippocampal
formation is the

• a. anterior thalamus.
• b. locus coeruleus.
• c. entorhinal cortex.
• d. subiculum.

4
Neurons in the field of CA1 of the hippocampus
are easily damaged when metabolic disturbances
set off a series of events that include the

• a. rapid proliferation of NMDA receptors.
• b. desynchronized firing of presynaptic axons.
• c. entry of calcium into the neurons resulting
  in excessively high levels of intracellular
  calcium.
• d. release of abnormally high levels of
  serotonin.

5
Rats are trained in a milk maze

• a. to reduce the effects of tactile stimulation.
• b. to test their spatial perception and memory.
• c. to avoid using food as a reinforcing
  stimulus.
• d. To assess their stimulus-response learning.

6
A targeted mutation that increased the production
of NMDA receptors with a particular subunit __
leading to enhanced long-term potentiation.

• a. caused production of slightly longer EPSPs,
• b. caused development of an increased number of
  calcium channels,
• c. that is less likely to cause damage from
  seizures or anoxia,
• d. that causes production of increased levels of
  CaM-KII,

7
Behaviors closely associated with the presence of
hippocampal theta activity include

• a. wakefulness and sleep
• b. walking and running
• c. drinking
• d. reproductive behaviors

8
The original function of the hippocampus may have
been to

• a. regulate an animals circadian rhythms.
• b. help an animal recognize new stimuli.
• c. regulate an animals metabolism in response
  to environmental changes.
• d. help an animal navigate in its environment.
