In a conditioned emotional response (CER) study, a tone is paired with a foot shock for a rat. After several trials, the tone alone is a CS that can elicit fear emotional responses. Which of the following is true of the anatomy of this fear response?
A) The central nucleus of the amygdala integrates the pairing of tone and shock information.
B) Tone information is relayed directly to the central nucleus of the amygdala.
C) The lateral nucleus of the amygdala integrates the pairing of tone and shock information.
D) Damage to the lateral nucleus of the amygdala impairs perceptual learning, but not CER learning.
E) Damage to the central nucleus of the amygdala impairs perceptual learning, but not CER learning.
Question 2
In a conditioned emotional response (CER) study, a tone is paired with a foot shock for a rat. After several trials, the tone alone is a CS that can elicit fear emotional responses. Which of the following is true of the physiology of this fear response?
A) Damage to the lateral nucleus of the prefrontal cortex impairs CER learning.
B) Tone-shock pairings rapidly decrease the electrical activity of the lateral nucleus of the amygdala.
C) Damage to the central nucleus of the amygdala impairs CER learning.
D) Activation of the lateral nucleus of the amygdala during CER training blocks the formation of the CER.
E) CER learning is an example of perceptual learning.
The threespine stickleback (Gasterosteus aculeatus) has been used as a model organism for the study
