  5. In the first monkey, 96 microwires were implanted in the 1. left dorsal premotor cortex (PMd, 16 wires) 2. left primary motor cortex (MI, 16 wires) 3. left posterior parietal cortex (PP, 16 wires) 4. right PMd and MI (32 wires) 5. right PP cortex (16 wires) In the second monkey, 32 microwires were implanted in the 1. left PMd (16 wires) 2. left MI (16 wires) Recordings of cortical neural ensembles began 1-2 weeks after the implantation surgery and continued for 12 months in monkey 1, and 24 months in monkey 2.
