How Your Cat Is Making You Crazy: Article on Jaroslav Flegr and his research into a parasite shared by humans and their cats. The research shows how T. gondii “can turn a rat’s strong innate aversion to cats into an attraction, luring it into the jaws of its No. 1 predator. Even more amazing is how it does this: the organism rewires circuits in parts of the brain that deal with such primal emotions as fear, anxiety, and sexual arousal.”
If a parasite can control the behavior of infected rats, as this one does, could our thoughts be influenced by the same or similar sources? Are all our thoughts our own, or are we just as susceptible to parasitic influences as we are to marketing?
