Accepted Answer

Emotional learning

Question 3

Which statement best describes the evolutionary history of the limbic system?

Accepted Answer

It is phylogenetically older than the cerebral cortex.

Question 4

Long-term memory formation requires which of the following processes?

Accepted Answer

RNA and protein synthesis

Question 5

A person is able to remember how to ride a bicycle but cannot recall facts about world history. Which types of memory are intact and impaired, respectively?

Accepted Answer

Procedural memory intact; semantic memory impaired

Question 6

Which of the following best describes the function of the limbic system?

Accepted Answer

Processing olfactory information and basic emotional drives

Question 7

Which of the following is an example of working memory?

Accepted Answer

Remembering a phone number just long enough to dial it

Question 8

A lesion in which of the following structures would most likely impair the ability to form new long-term memories?

Accepted Answer

Hippocampus

Question 9

Which of the following best differentiates short-term memory from long-term memory at the molecular level?

Accepted Answer

Long-term memory requires both RNA and protein synthesis; short-term memory does not.

Question 10

Which of the following is NOT a subdivision of long-term memory?

Accepted Answer

Working memory

Question 11

A patient with a lesion in the cingulate gyrus would most likely have difficulty with which of the following?

Accepted Answer

Processing emotional responses

Question 12

Which of the following best explains why the limbic system is essential for survival?

Accepted Answer

It processes olfactory cues and basic emotional drives necessary for survival.

Question 13

Which of the following statements about the limbic system is TRUE?

Accepted Answer

It forms a ring around the brain stem and is involved in emotion.

Question 14

Which of the following best describes semantic memory?

Accepted Answer

Memory of facts and general knowledge

Question 15

A patient is unable to remember events from their own life but can recall general facts. Which type of memory is impaired?

Accepted Answer

Episodic memory

Question 16

Which of the following best explains why long-term memory formation is disrupted by inhibitors of protein synthesis?

Accepted Answer

Long-term memory formation depends on RNA and protein synthesis for synaptic changes.

Question 17

Which of the following is a correct sequence for the flow of olfactory information involved in emotional processing?

Accepted Answer

Olfactory bulb → limbic system → hypothalamus

Question 18

Which of the following best describes the role of the septal nucleus in the limbic system?

Accepted Answer

It is involved in the regulation of emotional and reward pathways.

Question 19

A researcher is studying the molecular basis of memory. Which equation best represents the requirement for long-term memory formation?

Accepted Answer

$$Long	ext{-}term\ memory \propto RNA\ synthesis + Protein\ synthesis$$

Question 20

Which of the following is most likely to be impaired in a patient with bilateral hippocampal damage?

Accepted Answer

Formation of new long-term memories
