Verified
The receptor sites of receiving neurons have been observed to increase following
A) priming.
B) the serial position effect.
C) long-term potentiation.
D) administration of propranolol.
Receptor Sites
Specific locations on cell membranes or within cells where chemical substances, like neurotransmitters or hormones, bind to trigger a physiological response.
Long-Term Potentiation
A boost in the potency of synaptic connections after stimulation with high frequencies at a chemical synapse, believed to be a process underlying learning and memory.
Neurons
Specialized cells in the nervous system that transmit information through electrical and chemical signals.

Final Answer :
C
Explanation :
Long-term potentiation (LTP) is a long-lasting increase in the strength of the synaptic connections between neurons. LTP has been shown to increase the number of receptor sites on receiving neurons, which can lead to more efficient neural communication. Priming (A) refers to the effect of a previous stimulus on the processing of a subsequent stimulus, and it does not directly relate to receptor site increase. The serial position effect (B) refers to the phenomenon where items at the beginning or end of a list are more easily remembered than items in the middle, and it also does not relate to receptor site increase. Administration of propranolol (D) is a beta-blocker medication that can block certain receptors, but it does not directly cause an increase in receptor sites.
