Monkeys Control Avatars With Thoughts Alone

Monkeys equipped with brain-computer interfaces (BCIs) have demonstrated the ability to navigate virtual environments using only their thoughts. Researchers implanted multiple electrode arrays into the motor and premotor cortex areas of three rhesus macaque monkeys. These implants allowed an AI model to interpret brain signals, enabling the monkeys to control avatars in diverse virtual settings.

The experiments allowed monkeys to control virtual objects from various viewpoints, including navigating through virtual buildings. Scientists believe this approach taps into higher-level, abstract planning of movement, offering a more intuitive control method compared to current BCIs that can be frustrating for users. This research could pave the way for intuitive control of electric wheelchairs and exploration of virtual worlds for individuals with paralysis.

While the technology shows promise, human trials are still some time away due to the need for precise mapping of human brain areas. However, the flexibility shown by the monkeys in adapting to different virtual contexts is seen as a significant advancement. Previous human trials have shown simpler BCIs enabling control of drones and text generation through thought.
