What neurotransmitter is associated with feelings of arousal and mood regulation?

Norepinephrine is indeed associated with feelings of arousal and mood regulation. This neurotransmitter plays a crucial role in the body's response to stress and is involved in the regulation of alertness and arousal. It activates the body's fight-or-flight response, leading to increased heart rate and heightened awareness. Additionally, norepinephrine influences mood; imbalances in norepinephrine levels have been linked to mood disorders such as depression and anxiety.

Understanding norepinephrine’s function in arousal and mood highlights its importance in both mental health and physiological responses, making it a key player in emotional states and reactions to stressors.
