“The thoughts is its personal place,” Milton wrote in Paradise Misplaced, “and in it self could make a Heav’n of Hell, a Hell of Heav’n.” Whereas that is psychologically true — the thoughts is, in any case, how consciousness renders actuality — it’s not all the time physiologically true: The mind and physique out of which the thoughts arises are a bodily system, contiguous with each bodily power and course of that touches it, permeable to myriad invasions and reconfigurations that alter the system and thus rework the thoughts into a completely completely different place.
Nowhere is that this haunting vulnerability to transformation starker than within the case of the fungus Ophiocordyceps unilateralis and the thoughts of the carpenter ant, difficult our most elemental intuitions about company, about autonomy, about what a self is.
A part of a bunch generally known as “zombie fungi,” Ophiocordyceps hijacks an insect, driving it to disperse the fungus’s spores on the worth of its personal life. In his altogether fascinating guide Entangled Life: How Fungi Make Our Worlds, Change Our Minds & Form Our Futures (public library), mycologist Merlin Sheldrake particulars this sinister puppet present of biochemistry:
As soon as contaminated by the fungus, ants are stripped of their instinctive worry of heights, depart the relative security of their nests, and climb up the closest plant — a syndrome generally known as “summit illness.” Sooner or later the fungus forces the ant to clamp its jaws across the plant in a “demise grip.” Mycelium grows from the ant’s toes and stitches them to the plant’s floor. The fungus then digests the ant’s physique and sprouts a stalk out of its head, from which spores bathe down on ants passing under. If the spores miss their targets, they produce secondary sticky spores that stretch outward on threads that act like journey wires.
Zombie fungi management the habits of their insect hosts with beautiful precision. Ophiocordyceps compels ants to carry out the demise grip in a zone with simply the fitting temperature and humidity to permit the fungus to fruit: a peak of twenty-five centimeters above the forest flooring. The fungus orients ants in accordance with the path of the solar, and contaminated ants chew in synchrony, at midday. They don’t chew any previous spot on the leaf’s underside. Ninety-eight p.c of the time, the ants clamp onto a significant vein.
As a result of the marks left on leaf veins by these death-bites are so distinct, proof of them could be discovered within the fossil report way back to the Eocene, almost fifty million years in the past — the daybreak of recent fauna, a time when forests coated the Earth from pole to pole. Sheldrake displays:
It’s probably that fungi have been manipulating animal minds for a lot of the time that there have been minds to govern.

However in contrast to the mind-controlling parasite that drives wasps to desert their colonies, Ophiocordyceps appears to govern the thoughts by means of the backdoor of the physique: Analysis signifies that the fungus could not have a bodily presence within the ant’s mind, as an alternative secreting chemical compounds that activate the ant’s muscle groups and steer its central nervous system (which we now know is the evolutionary underpinning of consciousness).
Couple with the brand new science of how fungi are altering human minds, then revisit Lewis Thomas’s magnificent meditation on how the connection between a jellyfish and a sea slug illuminates the thriller of the self.
