Dr. Nicolelis primarily researches brain activities using one of the lab's favorite monkys, Arora. His lab is one of the few cognitive science plus brain function labs which have created ape-to-computer-to-machine interfaces such that, in at least one experiment, the ape ceases using one of their real arms because they can use a mechanical arm more easily to get the same rewards.
