Monkeys Use a Brain-Controlled Virtual Hand To "Feel" Virtual Objects

An international team of researchers has developed a brain implant that enables monkeys to examine virtual objects by means of a virtual arm controlled by their brain...In a task involving a choice between two visually identical objects, the monkeys were able to distinguish between a reward-producing object, which was associated with an electrical stimulation when 'touched', and an object that produced neither electrical stimulation nor a treat. This shows that the brain can decode information about the sense of touch without any stimulation of the animal's skin, says Nicolelis. His team reports their results today in Nature. more
