@Eli7 #7 is a bit misleading. That there is no definitive conclusion means little as it pertains to scientific studies. Almost no area of study have among all studies a "definitive conclusion". There are however several more recent studies that point towards behavioural changes in humans exposed to the parasite. Some of the things are relatively easy (at all possible) to measure such as increased leves of testosterone and dopamine, others such as the exact changes this causes in an individual persons behavioral patterns are a bit more fuzzy. It's true that you can't (based on current research) say "this is exacly what happens to everyone infected", but you can say that there is substantial evidence to support the theory that T. Gondii can and does cause behavioural changes in infected humans. But as always: Further research is needed.
