Researchers have unveiled a new intracortical brain–computer interface (BCI) that enables macaque monkeys to navigate complex 3D virtual reality environments using only their brain activity. Developed using neural signals from multiple brain regions, including the primary motor cortex and both dorsal and ventral premotor cortices, the system significantly improves the precision and flexibility of decoding real-time movement compared to earlier BCIs. The study demonstrates how combining signals from these areas allows for more natural and continuous control in immersive digital spaces.
In experimental trials, the monkeys successfully completed navigation tasks in VR without any physical movement, relying solely on neural input. They also showed the ability to learn and improve performance over time, with the system generalizing across different tasks without requiring retraining. Researchers highlight the potential of this technology for real-world applications, particularly in assisting people with paralysis to control wheelchairs, prosthetic devices, or explore virtual environments. The findings mark an important step toward more intuitive and adaptive brain-controlled interfaces.
