english: 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.
non_english: A da bi dobio nagradu, kap soka od pomorandže, koga majmuni obožavaju, ova životinja mora da otkrije, da izabere jedan od ovih objekata dodirivanjem, ne gledanjem, već dodirivanjem, jer svaki put kada ova virtuelna ruka dodirne jedan od objekata, električni impuls se vraća u mozak životinje opisujući finu teksturu površine ovog objekta, te životinja može da proceni koji je pravi objekat koji mora da zgrabi, a ako tako postupi, dobija nagradu, ne pomerivši ni jedan mišić.
