But more recently, scientists have begun to determine how oxytocin functions in the human brain — or, more specifically, how it malfunctions. Studies have shown that people with autism tend to have low levels of oxytocin, as well as hyperactivity in the amygdala, where most oxytocin receptors are located. The amygdala is also where memories are formed, and where our brains process and assign emotional meaning to sensory information — that is, where we turn perception (seeing someone smile) into "neuroception" (understanding the feeling of happiness that the smile reflects), according to Stephen Porges, a psychologist at the University of Illinois in Chicago. So, misfirings in the amygdala, in tandem with low oxytocin, may help explain why people with autism have trouble distinguishing between happy expressions and angry ones, making social interaction difficult and unpleasant.I know what it is like not to know what to do in social situations but I have no idea what it would be like not to be able to read peoples facial expressions and body language. It is one thing to learn this but a whole other thing to feel it.
