How does the brain of an unfaithful person work? – Part IV
Hormones and infidelity
People who have more testosterone and vasopressin are more unfaithful. These hormones are more related to dominance, aggressiveness and sexual appetite. They activate brain areas related to possession and care of genes.
An average man who is more unfaithful releases more testosterone and increases sperm count.
Oxytocin and prolactin slow down the process of infidelity. Oxytocin decreases over the years. Women release more oxytocin due to stimulation.
Psychology of the pain of infidelity
The pain of feeling cheated is learned over generations and this process has a critical factor in childhood, particularly between 9 and 12 years of age when the connections of the cingulate gyrus, insula and mirror neurons mature.
The unfaithful person has patterns of comparison in his later generations. The victim acquires the pattern of suffering that his family has taught him.
Communities where there is a greater predominance of men have more violence, compared to communities where there are women, there is a greater predominance of equity, security and social understanding.
