Czech biologist Jaroslav
Flegrei is known for his statement that the common freeloader known as
Toxoplasma (Toxoplasma gondii) is able to "manage" the human brain.
Toxoplasma is which
usually affects cats, known with scientists through their "smart tactics."
Coming from a cat in a rodent parasite makes him fearless, directing poor
straight into the jaws of a cat. The freeloader multiplies in the cat, then the
feces is disqualified, thus again can get to the rodent.
Flegrei discovered that
people infected with the parasite, it is peculiar behavior like rats: slow
reaction, lethargy and reduced fear. But until recently, scientists did not
know the mechanism of the nervous system.
