Neuromodulator Phases

The discussion highlights the three distinct phases of neuromodulator activity throughout the day. In the first phase, dopamine and epinephrine peak shortly after waking, while the second phase sees a decline in these levels and an increase in serotonin. The third phase introduces a chaotic interplay of various neuromodulators during sleep, characterized by fluctuating levels of acetylcholine, dopamine, and serotonin. Understanding these phases can provide valuable insights into how our bodies function and respond to different stimuli throughout the day.
