Human medicines affect fish behavior

Human medicines that act on important signal systems in the brain make fish bolder, shows a new study on three-spined sticklebacks by researchers at Linköping University, Sweden. The results reinforce that the signal substances serotonin and dopamine play important roles in behavioral differences between individuals. Further, it shows that drugs that end up in the natural environment may have consequences for animal life. The study has been published in the Journal of Experimental Biology.
