MEXICO: In ground-breaking Star Trek-style experiments, scientists have successfully linked the brains of multiple rats and monkeys, creating a ‘brainet’ that allowed them to co-operate and learn as a superbrain.
In two separate experiments, reminiscent of the hive mind network of Star Trek’s Borg villains, the brains of monkeys and the brains of rats were linked, allowing the animals to exchange sensory and motor information in real time to control movement or complete computations.
In one example, scientists linked the brains of rhesus macaque monkeys, who worked together to control the movements of the arm of a virtual avatar on a digital display in front of them.
Each animal controlled two of three dimensions of movement for the same arm as they guided it together to touch a moving target.
In the rodent experiment, scientists networked the brains of four rats complete simple computational tasks involving pattern recognition, storage and retrieval of sensory information, and even weather forecasting.
Brain-machine interfaces (BMIs) are computational systems that allow subjects to use their brain signals to directly control the movements of artificial devices, such as robotic arms, exoskeletons or virtual avatars.
