Question

Low levels of this neurotransmitter are associated with anger, pessimism, and depression. Which neurotransmitter is this?

1) Serotonin
2) Dopamine
3) Norepinephrine
4) GABA

Answer 1

Low levels of the neurotransmitter serotonin are linked to feelings of anger, pessimism, and depression. Antidepressants can help correct this by increasing serotonin levels in the brain.

Step-by-step explanation:

The neurotransmitter associated with anger, pessimism, and depression when found at low levels is serotonin (5-hydroxytryptamine or 5-HT). Serotonin plays an important role in mood regulation and other vital functions within the central nervous system. Low serotonin levels are thought to be a contributing factor to depression, and medications known as antidepressants help to correct this imbalance. These antidepressants work by increasing serotonin levels in the brain, which can help alleviate the symptoms of depression, allowing individuals to lead happier and more productive lives.
