>"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 hum…

waiting for the rule 34...

Ask an addict.

Even simpler, put some chocolate biscuits on a plate in view of where you sit and attempt to avoid the action of indulging.

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

I think it's much more probably that ants have some high-level chemical signals that the fungus uses. One to climb, and another to bite maybe?

Ants already use pheromones to communicate.

Look at this picture of the final stage, after the 'stalk' sprouts from the ants head. Pretty haunting. https://upload.wikimedia.org/wikipedia/commons/8/85/Ophiocor...

Netflix has a new fungus documentary out called "Mushrooms" I think that shows this scene. This fungus is now being used for Cancer research.

I tried but somehow the biscuits kept vanishing. I can't explain it.

Honest question -

Is this truly different from what social networks can do to gullible people? Or from what religion had been doing for centuries?

Yes, those are controlling the brain. In this instance, the fungus seems to be skipping the brain and just working the muscles.

Earlier quoted context omitted.

That seems more probable and way more intuitive, but I don't really understand how the mechanics of that mesh with what the researchers are saying happens to the ant muscles.

Honest answer: yes, being indoctrinated is pretty different than having your muscles literally controlled by a third party, if only for the illusion of agency
