Tracked metric

Electrodes per implant

Number of recording electrodes (channels) on a single implant — the rough ceiling on how much neural signal it can read. Neuralink's N1 and Precision's Layer 7 each carry 1,024, versus the 96 of the original BrainGate array.

Three ways into the brain

BCIs trade off signal quality against surgical risk. Penetrating arrays (Neuralink) read the most; surface arrays (Precision) sit on the brain; vascular devices (Synchron) avoid open-brain surgery entirely. The tracker compares all three.
