According to CoinMeta, recent research by the Brain Atlas and Brain-like Intelligence Laboratory at the Institute of Automation, Chinese Academy of Sciences, has revealed explicit three-dimensional spatial representations of hand positions in the primary motor cortex (responsible for motor execution) and the dorsal premotor cortex (responsible for motor planning) of macaques. The research team found that the brain not only encodes how to move but also maintains a “three-dimensional hand position map” similar to GPS. More importantly, just a few dozen neurons encoding hand positions are sufficient to accurately decode three-dimensional hand trajectories, providing a solid neuroscientific basis for a more efficient new generation of brain-computer interfaces. This research finding was recently published in the neuroscience journal “Neuroscience”.
