Textbook Question
Chapter 37, Problem 6TYU
Suppose a particular neurotransmitter causes an IPSP in postsynaptic cell X and an EPSP in postsynaptic cell Y. A likely explanation is that

- B. the axon of cell X is myelinated, but that of cell Y is not.
- C. only cell Y produces an enzyme that terminates the activity of the neurotransmitter.
- D. cells X and Y express different receptor molecules for this particular neurotransmitter.
