Great article!!! I would be interested to hear an explanation of the overlaps of the three major n.transmitters in the ven diagram. Is this to day that when Adrenaline (Norepinephrine) and Serotin both exist you have anxiety? And when dopamine and serotonin both exist you have agression or is this low levels? What is the source of this graphic? Cheers!
All of these neurotransmitters are present in every person’s brain at all times. The effects depend on how much of each is actually available at any given time.
