A research team led by Dayna Forsyth has examined how psilocybin influences the social behavior of the mangrove rivulus (Kryptolebias marmoratus) in a study published in Frontiers in Behavioral Neuroscience. Because of its pronounced territorial and aggressive behavior, this fish species is considered a suitable model for behavioral biology research.
For the behavioral experiment, adult mangrove rivulus were exposed once for 20 minutes to a water-based psilocybin concentration of 3,000 micrograms per liter (higher doses of up to 12,000 µg/L were examined to analyze tissue absorption). In the standardized paired interactions that followed, activity and aggressive “swimming bursts” decreased significantly, meaning the short, rapid movement patterns that serve as markers of aggressive behavior in this experimental model. Because the observed effects varied widely between individuals despite the genetic homogeneity of the laboratory line, the researchers concluded that the effect is largely independent of the respective genotype.
In the authors’ assessment, the findings provide further indications that psilocybin can produce behavior-modulating effects in animal models and offers a preclinical basis for future clinical research.
