In a new study from Japan, results have shown that virgin mice preferred watching mice fight videos and receiving morphine injections rather than watching mice erotica and mice sniffing videos. The research was done by Japanese scientists Shigeru Watanabe from Keio University, Kazutaka Shinozuka with the RIKEN Brain Science Institute and Takefumi Kikusui from Azabu University and was published in the scientific journal "Animal Cognition."
Although Japan does not have a big drug problem, this study may partly explain why violent anime is so popular in Japan and all over the world. It may also partially reveal why many young Japanese men and women are not interested in sex these days.
About this study, Barbara Kenig at the University of Zurich in Switzerland told New Scientist: "There is a debate over whether time spent with a specific cue is a good proxy for preference. Mice might just need longer to gain information on whether the objects signal any kind of danger."
