A team of researchers has managed to have primates control a three-dimensional virtual environment solely with their brain activity. The study, published in a scientific journal, shows how the monkeys can move an avatar towards virtual targets without moving a muscle. To achieve this, they implanted electrodes in the motor cortex that capture signals related to movement intention. An algorithm translates those signals into commands for the digital world.
Electrodes and Algorithms to Read Movement Intention 🧠
The system is based on a set of microelectrodes implanted in the monkeys' motor cortex. While the animals imagined actions like reaching for an object, the device recorded specific neural patterns. A machine learning algorithm processed this data in real time and converted it into instructions to move an avatar in a 3D space. The monkeys learned to generate the appropriate signals to reach specific points, demonstrating that it is possible to control virtual environments without direct physical feedback. The advance opens the door to more precise neural prosthetics.
The Day the Monkeys Surpassed Us at Playing Without a Controller 🐒
While you're sweating bullets looking for the TV remote between the sofa cushions, these monkeys are already controlling a virtual world with their minds. No trained thumbs, no gamer reflexes: pure mental power. The most ironic thing is that, with this advance, a primate could finish a video game before you find the power button. Of course, for now they don't know how to order pizza for delivery.
