Researchers at the Institute of Automation, Chinese Academy of Sciences report that macaque primary motor cortex (M1) and dorsal premotor cortex (PMd) contain explicit three-dimensional representations of hand position. The team found the brain maintains a GPS-like 3D hand-position map and that just tens of position-encoding neurons can accurately decode 3D hand trajectories, providing a neural-science basis for more efficient next-generation brain-computer interfaces.
