Arousal Chemical Signature

Meaning

The Arousal Chemical Signature represents the distinct, measurable pattern of neurotransmitter and neuromodulator concentrations released within specific brain regions that collectively define a state of physiological and psychological arousal. This signature is not a single compound but a dynamic ratio of key signaling molecules, including acetylcholine, norepinephrine, dopamine, and hypocretin/orexin. The balance of this signature dictates an individual’s capacity for focused attention, motivation, and reaction speed, linking directly to mental performance and stress response.
