The study, conducted by the Weizmann Institute of Science in Israel, examined the chemical signals found in tears and their effects on the human brain. According to results obtained in rodents, emotional tears contain chemical signals that serve a protective function, restraining aggressive behavior in men.
In the study, participants played a money game while exposed to female tears or saline, and the tears caused a significant decrease in aggression. Brain scans revealed decreased activity in brain networks associated with aggression; This supports the theory that tears protect against aggression by acting as a chemical blanket.
