Identify the primary neurotransmitters discussed in your text. Distinguish between them based on their proposed functions. Propose one potential impact if a person has particularly low levels of each neurotransmitter.

Question

What will be an ideal response?

Answer 1

Acetylcholine is a neurotransmitter associated with memory function, arousal, and movement. Therefore, someone struggling with too little acetylcholine would have difficulty in forming new memories, making movements, and maintaining normal levels of arousal. Dopamine is a neurotransmitter associated with pleasure sensation and appetite suppression. Someone low in dopamine might overeat and have very little motivation to seek something pleasurable. Endorphins are critical chemicals for providing pain relief. Someone low on endorphins would experience more pain than normal. Glutamate is a neurotransmitter responsible for learning and memory enhancement. Obviously, if someone is low in glutamate, learning and memory would be reduced. Norepinephrine is a neurotransmitter implicated in arousal, mood, and appetite suppression. Someone with too little norepinephrine could suffer from low arousal, low mood, and decreased appetite suppression. Serotonin is a neurotransmitter that has been shown to play a role in mood, sleep, and appetite. Low levels of serotonin would lead to low mood, a lack of sleep, and a change in appetite. Lastly, GABA is indicated in sleep, anxiety, and tension. Low levels of GABA might lead to sleep disturbance, anxiety, and increased tension.
