# Full-Bandwidth Brain-Computer Interface **Entity class:** Neurotechnology horizon **Domain:** Brain-computer interfaces / Human-computer interaction **Maturity:** Developed ## Definition A full-bandwidth brain-computer interface is a proposed system capable of reading and writing a sufficiently rich range of neural signals to support fluid, high-dimensional interaction. ## Mechanism and significance It remains a horizon concept beyond current interfaces; progress requires improvements in spatial coverage, temporal precision, biocompatibility, decoding, stimulation, and long-term stability. ## Relationships - **Research dossier:** [[research/ASI and RSI Timeline Research Moonshots|ASI and RSI Timeline Research Moonshots]] - **Ontology route:** [[ASI and RSI Timeline Ontology#Neural Decoding and Cognitive Systems|Neural Decoding and Cognitive Systems]] - **Primary fields:** [[Neural Decoding]] · [[Brain-Computer Interfaces]] · [[Functional Magnetic Resonance Imaging]] - **Adjacent concepts:** [[Neuralink Electrophysiological Data]] · [[Scaling Laws for Neural Foundation Models]] · [[Full-Dive Virtual Reality]] · [[Direct Cognitive Communication]] ## Sources and provenance - [[research/ASI and RSI Timeline Research Moonshots|ASI and RSI Timeline Research Moonshots]] — immediate source for this node's role in the broadcast research map. ## Evidence boundary The research dossier establishes why this entity or concept belongs in the Moonshots ontology. Time-sensitive organizational, product, policy, and performance claims should be checked against the linked primary source or a current authoritative source before reuse as settled fact. ## Simple Reminders, Quotations, and Thoughts > Functional MRI has hard spatial and temporal limits, but it is already supporting vision, language, and dream decoding. Reaching full-dive virtual reality and full-bandwidth brain-computer interfaces will require much higher precision, yet every frontier begins with primitive systems—and Brain-IT, Jack Gallant, and Jean-Rémi King are part of that beginning. > **— Adapted from Alexander Wissner-Gross**, *MOONSHOTS Live, October 2026* [[reminders/Neural Interfaces/Brain Decoding Is on the Road to Full-Bandwidth Interfaces by Alexander Wissner-Gross|Brain Decoding Is on the Road to Full-Bandwidth Interfaces by Alexander Wissner-Gross]]
