Parasites can dramatically change the behaviour of their hosts. A parasitic worm turns a tropical ant berry-red and causes it to climb high, attractive prey for birds, the worm’s next host. A mouse infected by toxoplasma gondii no longer fears cats – making it easier for the parasite to be eaten by its next host, a cat. A jewel wasp precisely injects neurotoxins into its cockroach prey’s brain. These parasite manipulations can tell us how brains, including our own, work normally.
