What happens when you give a naturally aggressive fish psilocybin?
Researchers in Canada decided to find out.
In a new study, mangrove rivulus fish exposed to psilocybin showed a significant reduction in aggressive swimming bursts.
But here's what makes the findings interesting.
Other forms of social behaviour remained largely unchanged, although overall movement also decreased.
This raises an interesting question about whether psilocybin can influence specific forms of aggression without broadly suppressing social interaction.
It's early animal research, with no established implications for treating aggression in humans.
But it's another fascinating direction for psychedelic research.
