The classically conditioned fear response in rats results primarily from
A) protein synthesis in postsynaptic neurons in the amygdala.
B) fatigue of motor neurons responsible for freezing.
C) decreased release of neurotransmitter by sensory neurons and interneurons in the amygdala.
D) increased release of neurotransmitters by neurons in the sensory systems responding to the conditioned stimulus.

Question

Quizplus · Accepted Answer

Classical conditioning involves the formation of a strong association between a neutral stimulus and a biologically significant stimulus (such as a shock or pain). This association leads to the development of a conditioned fear response, which can be measured as freezing behavior in rats. Recent research suggests that this fear response is primarily due to an increase in protein synthesis in postsynaptic neurons in the amygdala, a brain region involved in emotional processing and fear learning. This protein synthesis is thought to be necessary for the consolidation and maintenance of the fear memory. Therefore, Option A is the best choice.
