Prediction of Reach Goals in Depth and Direction from the Parietal Cortex.

摘要: Summary The posterior parietal cortex is well known to mediate sensorimotor transformations during the generation of movement plans, but its ability control prosthetic limbs in 3D environments has not yet been fully demonstrated. With this aim, we trained monkeys perform reaches targets located at various depths and directions tested whether reach goal position can be extracted from signals. location was reliably decoded with accuracy close optimal (>90%), occurred also before onset. These results, together recent work showing a reliable decoding hand grip same area, suggest that suitable site decode entire prehension action, considered development brain-computer interfaces.
