Amiability Can be Associated with Your Immune System
From the perspective of evolution, the amiability of humans might have less to do with their brand and more associated with the immune system’s exposure to pathogens. At the University of Virginia School of Medicine, researchers have come up with a theory that interferon-gamma (IG), a component that assists the immune system combat invaders, was associated with social behavior, which is one of the primary ways one gets in contact with pathogens.
When tested the theory in mice, the researchers found that IG acted as a brake to the prefrontal cortex of the brain, primarily putting halting aberrant hyperactivity that results in adverse changes in your social behavior. Furthermore, when they blocked the IG molecule, the prefrontal cortex of mice became quite hyperactive, leading to less sociability. When the function was restored, the mice’s brains began to function normally, so did their social behavior.
