Full Specification Comparison
| Specification | BCI (Cortical) | Neuromodulation | PNI (Peripheral) |
|---|---|---|---|
| Target | Brain cortex | Deep brain / nerves | Peripheral nerves |
| Invasiveness | High | High | Moderate |
| FDA Approved | Breakthrough only | Yes (DBS, VNS) | Limited |
| Applications | Paralysis, communication | Parkinsons, epilepsy, pain | Prosthetics, pain |
| Signal Direction | Bidirectional | Stim only | Bidirectional |
| Key Companies | Neuralink, Synchron | Medtronic, Abbott | Paradromics, Axoft |
| Patients Worldwide | <100 | 200K+ | <1,000 |
Expert Verdict
BCIs target thought-driven control for paralysis; neuromodulation is FDA-approved for Parkinsons, depression, and pain; PNI offers natural motor control without brain surgery.
