Abnormal structure or function of the amygdala is a common component of neurodevelopmental disorders - Cynthia M. Schumann et.al.
The amygdala, perhaps more than any other brain region, has been implicated in numerous neuropsychiatric and neurodevelopmental disorders. It is part of a system initially evolved to detect dangers in the environment and modulate subsequent responses, which can profoundly influence human behavior. If its threshold is set too low, normally benign aspects of the environment are perceived as dangers, interactions are limited, and anxiety may arise. If set too high, risk taking increases and inappropriate sociality may occur.
The Neuroscience of Respect - Gregg Ward
When you feel disrespected by someone else, your Reptilian brain perceives that behavior toward you as a threat, even if its behavior that the person doing it thinks is perfectly respectful. Within less than a second, your self-preservation instincts kick in and the fight, flight, freeze response is triggered. Then, that threat warning is quickly passed onto your Limbic system, which is centered within a very important part of your brain called the Amygdala, an organ that some of us have heard about and most of us have trouble pronouncing.
