This is insane
Scientists just built an intracortical brain computer interface (iBCI) that let monkeys navigate a 3D virtual world using only their thoughts.
Electrodes implanted in the motor and premotor cortex captured brain activity, and an AI-based neural decoder trained on this data translated it into continuous velocity commands for real-time movement.
The monkeys moved through complex environments, avoided obstacles, and adapted dynamically without any physical movement. Even more impressive, the system worked across tasks without retraining.
The key insight: decoding intention (premotor cortex) worked better than decoding movement itself. This marks a shift from movement based control to true intent-based brain interfaces.
Acceleration is everywhere
