Previously a major hurdle in brain-machine interface was the lack of an implantable neural interface /neural recording systems less than 10 – 100 µm in scale for transmitting and recording neural signals across multiple brain structures. As the bio sensors scale down and the distance between recording points decreases accordingly, the absolute accuracy of a neural read increases . Previously the EM signal had to be garnered and imbued through 2 mm of brain tissue and due to tissue absorption and beam spreading the fluency of functional transcription was both time consuming and expensive..
Previously the highest fidelity acquisition of brain signal could be achieved using bio sensors remotely "parked" between brain cells or means of short term intra-cellular penetration. Previously our approach to "mind translation" focused on the signal discharge of individual neurons rather than seeking "ease of acquisition "concerning composite equivocation of the entire neural signature .The smallest neural prosthetic previously occupied approximately 100 µm2 of silicon real estate .Packing the same functionality onto a smaller footprint is now plausible. Thinned, multi-substrate integration to meet the volume requirements while keeping the overall CMOS area constant resolves the issue of scale but requires substantial human study . Scaling the active electronics to appropriate dimensions is clearly a win for the Mind Augment /Mind Assessment Industry -Tru Christie ,Proxy Cybernetics
