How many electrodes does Neuralink's implant have, and how are they placed?

The N1 implant used in Neuralink's human studies has 1,024 electrodes spread along 64 flexible threads, 16 per thread, each thread thinner than a human hair. A surgical robot, the R1, inserts the threads one by one a few millimetres into the hand and arm area of motor cortex, steering around visible blood vessels, while the sealed implant replaces a disc of skull about 23 mm across. The first participant was implanted in January 2024, and the company reported about twenty participants by early 2026.
