>"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).

The Last Of Us explored this concept using a fictional version of this same fungus that infected humans instead

Maybe not that drastic but check this out:

Wouldn't that require the fungus to have a nervous system of its own?

The article reads like it either does or it somehow manipulates the nervous system of the host without actually infecting the brain.

Yeah it's really weird. Animal time scales (needed to control muscles) seem much faster (order of ms) than fungus time scales (order of seconds for a very fast one)

It seems to me it requires the whole fungus to assembly itself in some kind of "fungus brain". Really fascinating stuff
