'Zombie ant' brains left intact by fungal parasite
>"Normally in animals, behavior is controlled by the brain sending signals to the muscles, but our results suggest that the parasite is controlling host behavior peripherally," Hughes said. "Almost like a puppeteer pulls the strings to make a marionette move, the fungus controls the ant's muscles to manipulate the host's legs and mandibles."Probably the most "And I Must Scream" moment in mother nature. Imagine a human gets infected by a parasite that controls their body but leaves their brain intact to observe what their body is doing (and probably drugged to hell as the article implies).
