Details | To explore how intentions may be used for neural prosthetic applications, we have implanted microelectrode arrays in a high-level cortical area, the posterior parietal cortex (PPC), in human tetraplegics. We find that human PPC is very high dimensi-onal, coding a variety of variables including movements of both hands and both shoulders, observed actions, cognitive strategies, and memory-based decisions. This high dimensional coding is an advantage for neural prosthetics as a great deal of information can be read out from a single array in PPC. Tetraplegic patients cannot feel their bodies below the level of injury. To provide back somatosensati-on, in one tetraplegic participant we have intracortically microstimulated the primary somatosensory cortex with small electrical currents through microelectro-de arrays. The participant reported natural quality cutaneous and proprioceptive sensations: promising results for allowing natural-seeming somatosensory feed-back for more dexterous brain-control of robotic limbs. |
