Three methods that could be used to show that a neurotransmitter receptor is synthesized or localized in a particular neuron are:

Immunocytochemistry:
- This method involves using antibodies that specifically bind to the neurotransmitter receptor of interest. By applying these antibodies to thin sections of brain tissue, researchers can visualize the presence and distribution of the receptor within specific neurons. This technique allows for the anatomical localization of receptors in the context of the cellular structure.
In Situ Hybridization:
- This technique is used to detect specific mRNA transcripts within neurons. By using labeled probes that bind to the mRNA of the receptor, researchers can determine whether the receptor is being synthesized in a particular neuron. The presence of the mRNA indicates that the neuron has the capacity to produce the receptor protein.
Western Blotting:
- This method can be employed to detect the presence of the receptor protein in neuronal tissue. After isolating proteins from the neurons, researchers can use specific antibodies against the receptor to identify and quantify the receptor protein. This confirms not only the presence of the receptor but also its synthesis within the neuron.

These methods provide complementary information about the localization and synthesis of neurotransmitter receptors in specific neuronal populations.
