Which of the following neurotransmitters is associated with mood and sleep?

Dopamine
Norepinephrine
Serotonin
GABA

The correct answer is: Serotonin

Serotonin is a key neurotransmitter that plays a vital role in regulating mood and sleep. It is often referred to as the "feel-good" neurotransmitter because of its significant influence on emotional well-being. Low levels of serotonin have been linked to mood disorders such as depression and anxiety. In terms of sleep, serotonin is a precursor to melatonin, which is crucial for sleep regulation. Additionally, serotonin helps modulate various functions in the body beyond mood and sleep, including appetite and digestion. Its diverse roles make it a critical target for many antidepressant medications, which aim to increase serotonin levels in the brain to improve mood and alleviate symptoms of depression. The connection between serotonin, mood stability, and sleep patterns is widely recognized in both clinical practice and research, underlining its importance in mental health and overall well-being.
