I ordered this book, Meet Your Happy Chemicals by Loretta Graziano Breuning, PhD. The following is a summary of what the back book cover states about four brain chemicals. I thought learning about the chemicals would be useful in showing how our POV character or the antagonist could be deficient in
one or more of the chemicals, which could explain some of their behaviors.
Dopamine makes us jump for joy. Dopamine feels great so we try to get more. It rewarded our ancestors’ will to explore.
Endorphin helps us to mask pain. Our ancestors survived from predator attack because endorphin caused them to feel good. Exercise triggers endorphin so we can safely reach home. Laughing or crying triggers it too.
Serotonin is stimulated by the status aspect…the pride of associating with a person of a certain stature. It triggers our need for respect.
Oxytocin is stimulated by touch and by social trust. It flows when we stick with the herd and create social bonds. Herds protected our ancestors from harm.
In my WIP, Norman in the Painting, my protagonist, Jill, has a need for more dopamine and endorphin. Her inner fears cause her to love running. Her goal is to run three miles every day. The endorphin rush makes her feel safe. Her lack of dopamine causes her to have no desire to explore. She spent most of her years close to her hometown and has no interest in travel. I’ll make sure she will produce more dopamine that will help her grow in her character arc.
The antagonist has a severe deficiency in oxytocin and serotonin.
Does your character have a chemical deficiency?
