And to get a reward, a drop of orange juice that monkeys love, this animal has to detect, select one of these objects by touching, not by seeing it, by touching it, because every time this virtual hand touches one of the objects, an electrical pulse goes back to the brain of the animal describing the fine texture of the surface of this object, so the animal can judge what is the correct object that he has to grab, and if he does that, he gets a reward without moving a muscle.
