2190 Tutorial 10 Learning

When researchers implanted electrodes into a person’s hippocampus, they found cells sensitive to what?

• Color

• Location

• Temperature

• Rhyming

The basal ganglia are primarily responsible for which type of learning?

• Gradually learning habits, based on immediate feedback

• Acquiring and storing episodic memories

• Memories that people can easily describe in words

• Quickly adapting learned behaviors to new circumstances

What is meant by the “specificity” of LTP?

• LTP occurs in certain parts of the brain and not others.

• Nearly simultaneous stimulation by two or more axons produces LTP more strongly than does repeated stimulation by just one axon.

• LTP occurs only at the synapses that have been activated.

• LTP occurs only at glutamate synapses

What is one of the symptoms that a patient with hippocampal amnesia has?

• Mood disorders

• Confabulations

• Impairment in working memory

• Difficulties in storing episodic information

Anterograde amnesia is loss of memory for ________, whereas retrograde amnesia is loss of memory for ________.

• events after the damage . . . events before the damage

• factual information . . . personal experiences

• events before the damage . . . events after the damage

• personal experiences . . . factual information

In non-associative learning, the activation of the excitatory interneurons leads to ____; the activation of the inhibitory interneurons leads to ____.

• decreased firing of motor neurons; decreased firing of sensory neurons

• habituation; sensitization

• increased firing of sensory neurons; increased firing of motor neurons

• sensitization; habituation

Why does the patient's response to the researchers become increasingly positive, despite his inability to recall them due to the hippocampal amnesia?

• His hippocampus is gradually recovering and records the feelings to the researchers.

• His temporal lobe is not totally damaged.

• There still is classical conditioning in his amygdala.

• He has been habituated to the visit of the researchers by non-associative learning.
