Researchers at the University of Kentucky were interested in the link between low glucose levels and aggressive behavior… […]
When you go several hours without eating, your blood sugar drops. Once it falls below a certain point, glucose-sensing neurons in your ventromedial hypothalamus, a brain region involved in feeding, are notified and activated resulting in level fluctuations of several different hormones. Ghrelin, a hormone that increases expression when blood sugar gets low and stimulates appetite through actions of the hypothalamus, has been shown to block the release of the neurotransmitter serotonin. The serotonin system is incredibly complex and contributes to a number of different central nervous system functions. One of the many hats this neurotransmitter wears is modulation of emotional state, including aggression. […]
If you have a predisposition to aggression, low serotonin levels circulating in your brain may lead to altered communications between brain regions that wrangle aggressive behavior.
