Record the activity of a cat's brain ... for whom?

The law requires that experiments on animals be justified and be as painless as possible. It is one of the most difficult procedures for Dr Ménache to comprehend and to see the goal or it is usefulness, especially since no application is planned in human medicine.

In 2017, researchers implanted electrodes in the brain of small cats, in order to record the activity of their brain during a vision experiment. These sentient beings were slightly anesthetized, but it was still necessary to inoculate a muscle relaxant, in order to paralyze them, to avoid any movement. What do we understand? That the anaesthesia is incomplete - because the brain and the sight are solicited, and that the cats could thus feel the pain while being conscious.

It happens that some human patients wake up from anaesthesia during surgical operations. But more than pain, it is paralysis that terrifies them the most. Imagine the deep fear of these cats in this situation!
