Answer:
"Serotonin" neurotransmitter is MOST likely involved in Suzanne's symptoms
Step-by-step explanation:
Serotonin is an important chemical and neurotransmitter in the human body. It is believed to help regulate mood and social behavior, appetite and digestion, sleep, memory, and sexual desire and function. There may be a link between serotonin and depression. Serotonin is primarily found in the enteric nervous system located in the gastrointestinal tract (GI tract). However, it is also produced in the central nervous system (CNS), specifically in the Raphe nuclei located in the brain stem.
