Neuralink demonstrates a wireless brain-computer interface enabling Brad Smith, living with ALS, to compose text via thought. The implant records cortical activity, transmits it via Bluetooth, and employs AI-driven language models to interpret cursor movements. This innovation underscores potential applications in restoring communication and autonomy to individuals with motor impairments.

Key points

• Quarter-sized implant records neuronal activity from motor cortex.
• Wireless Bluetooth transmission interfaces with external computing.
• AI-driven decoders map neural signals to cursor movements and text.
• System restores real-time communication for ALS patients.
• Integrated language model generates predictive text and voice synthesis.

Why it matters: This breakthrough shifts paradigms in assistive neurotechnology, demonstrating a fully implantable BCI that restores communication without external sensors. It opens avenues for treating paralysis and other neurological deficits, offering improved reliability and user autonomy compared to traditional noninvasive interfaces.
