Hijacking the Brain

Parasite mind control is more precise than any horror film:

• Ophiocordyceps — drives muscles directly, parking the ant where the fungus grows best.
• Hairworms — fake brain chemicals that command a cricket to drown itself.
• Toxoplasma — can reduce rodents' aversion to cat odor while also affecting broader risk and activity patterns.
• The tools are chemical — fake neurotransmitters, brain cysts, and dopamine tweaks, not magic.
• Even we may be hosts — Toxoplasma is common in people worldwide, and scientists are still testing whether it nudges human behavior at all.
