Scientists have explained why the mouse is no longer afraid of cats
The American scientists were able to identify that toxoplasmosis can lead to changes in the brain, for example, mice with a history of infection, no longer afraid of cats, even after recovery.
Toxoplasma - a surprisingly simple, a habitat which may be any warm-blooded animal.
In the course of the experiment mice were infected with Toxoplasma, and then studied their reaction to the presence of traces of the cats, particularly smell.
It should be noted that typically a mouse, never even met cats, avoid the smell of urine, which animals mark territory.
But, as it turned out during the study, the mice after infection lose this fear, some have not returned to their usual state and after recovery.
