November 13 News — The Brain Atlas and Brain-inspired Intelligence Laboratory at the Institute of Automation, Chinese Academy of Sciences, has recently identified explicit three-dimensional spatial representations of hand position in the macaque primary motor cortex (responsible for motor execution) and dorsal premotor cortex (responsible for motor planning). The brain not only encodes "how to move" but also maintains a "3D hand position map" akin to GPS. Using just a few dozen neurons that encode position, researchers can precisely decode three-dimensional hand trajectories, offering a neuroscientific foundation for more efficient next-generation brain-computer interfaces. The findings were published in The Journal of Neuroscience.
