## Summary

Bypass eyes and ears. Read intent from cortex, write signals back. Once medical-only — now an arms race. Key sections include: BCI / Reading and writing to the brain.; ~ 86 billion neurons. We want to listen.; Listening from outside the skull.; Inside the skull . Closer to the spike.; From thought to cursor . From cortex to words.; Stimulate. The brain interprets.; Neuralink : more channels, robot surgeon.; Synchron . No craniotomy.; Precision Neuroscience . A film, not a needle.; Medical BCI already changes lives..
