AI & Neuroscience Convergence
Neuralink at 21 patients, Apple BCI protocol, neuromorphic computing
BCI technology reached inflection point in 2025-2026. Neuralink expanded its PRIME trial to 21 participants worldwide, with 5 patients controlling digital devices via thought. Apple announced a BCI HID input protocol, signaling consumer integration. Synchron demonstrated iPad control via its Stentrode. Neuromorphic chips (Intel Loihi 2, IBM NorthPole) achieve 100x energy efficiency. The consumer BCI timeline is accelerating from "5-10 years" to "3-5 years."

Brain-Computer Interfaces (2026 Update)
BCI technology crossed from research curiosity to clinical reality. Neuralink expanded its PRIME trial to 21 participants worldwide (up from 5 in mid-2025), with implant sites in Arizona and Florida and international registries open. Five patients with severe paralysis are actively controlling digital and physical devices with their thoughts.

Thought Decoding & Neural AI
AI systems can decode emotional states, predict depressive episodes (91% accuracy from wearable EEG), and reconstruct visual experiences from brain scans. The convergence of AI and neuroscience is bidirectional: brain research informs model architecture (attention mechanisms, memory systems, plasticity), while AI accelerates neuroscience discovery.

Timeline to Consumer BCIs
Apple's BCI HID protocol is the strongest signal yet that consumer brain-computer interfaces are approaching reality. Non-invasive BCIs (EEG headbands, near-infrared spectroscopy) are already shipping for meditation and focus applications. Clinical-grade BCIs for severe paralysis are in expanded trials. The timeline has compressed from "10+ years" to "3-5 years" for limited consumer applications.
