Poorly functioning sensory neurons

Would it be worse to have poorly functioning sensory neurons or motor neurons? Why? Neurons communicate using electrochemical communication. What part is “electric” communication and what part is “chemical” communication? Which do you think is more important? Why? Explain why having improper levels of neurotransmitters is not a good situation. Use a specific neurotransmitter to better explain your answer. If you had to live life without proper levels of one of your neurotransmitters, which would you choose? What would life be like? Is there anything you could do about it?
