Tachykinins and Aggression

Tachykinins, a family of neuropeptides, play a significant role in pain and aggression across various species, including humans. Research reveals that social isolation can lead to increased levels of Tachykinins, which in turn heightens aggressive behavior. This fascinating connection underscores the potential consequences of social isolation, as seen in both flies and mice, suggesting that the biological underpinnings of aggression are deeply rooted in our evolutionary history.
