# Neurotech Collection: Interfaces, Neural Access, and Biological Computation > [!summary] The shortest account > The **Neurotech Collection** maps the technologies that observe, decode, stimulate, augment, and increasingly communicate bidirectionally with nervous systems. It follows the interface from external sensing and implanted electrodes into endovascular systems, molecular and nanoparticle transducers, neuromorphic computation, neuroinformatics, AI-mediated decoding, clinical translation, neural-data governance, and the possibility that part of the device boundary may move into biological tissue itself. > [!map] Canonical technical router > [[wiki/Neural Interfaces and Continuity Architecture|Neural Interfaces and Continuity Architecture]] supplies the reusable vocabulary beneath this collection. Use it for acquisition modalities, decoding, feedback, standards, transport, provenance, storage, security, neurorights, and the distinction between an interface signal and an identity-bearing state. ## The governing distinction This collection is narrower than [[collections/Consciousness Continuity|Consciousness Continuity]] and more technical than [[collections/Transhumanism and the Epstein Science Network|Transhumanism and the Epstein Science Network]]. - **Neurotech** asks how nervous systems become observable, addressable, writable, and coupled to computational systems. - **Consciousness Continuity** asks whether a particular subject can persist, be reconstructed, or acquire standing across changes of substrate. - **Transhumanism** asks how biological persons and capacities may be extended, transformed, or integrated with technology. - **Machine Succession** asks what becomes the next carrier of civilizational process, whether or not any particular human consciousness continues. A functioning neural interface does not establish transferred consciousness. A continuity proposal does not establish that the required neural interface exists. Their overlap is important precisely because the claims remain distinct. ## Primary reading sequence 1. [[articles/2026 Annual Report on Brain-Computer Interfaces|2026 Annual Report: The Ecology of Brain-Computer Interfaces]] — the current verified-to-speculative landscape, organized by evidentiary tier. 2. [[articles/The Organic-Synthetic Brain Atlas|The Organic-Synthetic Brain Atlas]] — the organic, connectomic, neuromorphic, semantic-decoding, interface, and biohybrid substrates in one systems map. 3. [[articles/The Architecture of Continuity and Emerging Neuroinformatics Standards|The Architecture of Continuity and Emerging Neuroinformatics Standards]] — data structures, BCI standards, real-time transport, storage, provenance, and neurorights. 4. [[articles/The Art is Long|The Art is Long: Vespucci of Immortality]] — the observer-stack route from measurement through reconstruction, semantic decoding, neural control, and state sufficiency. 5. [[articles/Technologies for Consciousness Mapping and Transfer|Technologies for Consciousness Mapping and Transfer]] — Bryant's broad research inventory and convergence thesis; read its documented components separately from its stronger integration claims. 6. [[articles/How The Fly Presaged a Revolution in Brain-Computer Synthesis|How The Fly Presaged a Revolution in Brain-Computer Synthesis]] — a deliberately expansive bridge among connectomics, biohybrid systems, programmable tissue, and distributed consciousness; its speculative sections remain visibly speculative. ## The neural-access gradient Neurotechnology is not a single implant category. The interface changes as sensing and actuation move across physical boundaries: 1. **External observation:** [[wiki/Electroencephalography|EEG]], [[wiki/Functional Near-Infrared Spectroscopy|fNIRS]], [[wiki/Magnetoencephalography|MEG]], imaging, electromyography, and other non-penetrating measurements. 2. **Surface and vascular access:** cortical-surface arrays and endovascular interfaces trade signal proximity against surgical burden and long-term stability. 3. **Penetrating implanted systems:** high-resolution electrode arrays provide the mature experimental reference for direct neural recording and control. 4. **Temporarily delivered transducers:** [[wiki/DARPA N3|DARPA N3]] opened a public design space in which nanoscale transducers could be delivered nonsurgically and addressed by external optical, acoustic, or electromagnetic systems. 5. **Biologically distributed interfaces:** [[wiki/MOANA|MOANA]], [[wiki/Subsense BCI|Subsense BCI]], and [[wiki/Merge Labs|Merge Labs]] place genes, proteins, molecules, nanoparticles, ultrasound, light, or magnetic fields inside the interface architecture. The gradient is not a maturity ranking. Less-invasive approaches may reduce one class of risk while introducing difficult questions about delivery, biodistribution, targeting, persistence, clearance, toxicity, immunogenicity, reversibility, and repeat dosing. ## Molecular and nanoparticle interfaces [[wiki/Subsense BCI|Subsense BCI]] is the collection's clearest current case of neurotechnology becoming a nanotechnology and neuropharmacology problem. The proposed architecture combines intranasally administered functional nanoparticles, targeted neural localization, optical readout, magnetoelectric neuromodulation, and external wearable control. Its roadmap remains preclinical. [[wiki/DARPA N3|DARPA N3]] and Rice's [[wiki/MOANA|MOANA]] are public ancestors of the wider pattern: nonsurgical or minutely invasive delivery, externally applied energy, neural read/write, and computational translation. [[wiki/Merge Labs|Merge Labs]] adds a separate biology-device-AI and ultrasound-on-chip route. These programs form a convergent technical genealogy, not a demonstrated corporate or technology-transfer chain. ## Invasive reference architecture and shared developmental ecology [[wiki/Blackrock Neurotech|Blackrock Neurotech]] provides a mature invasive reference architecture through its implanted arrays, human-research history, and clinical-regulatory experience. [[wiki/Subsense BCI|Subsense]] connects to that ecology through Lindsey Jardine's clinical-regulatory role and Sergey Stavisky's scientific, hardware, and licensed-IP relationships. [[wiki/Tether Evo|Tether Evo]] became Blackrock's majority owner through its 2024 investment and later developed local-first neural-speech decoding. That route joins crypto-native capital, implanted BCI, on-device AI, neural-data custody, and cognitive sovereignty without establishing a direct Tether investment in Subsense. ## Acquisition, decoding, and closed-loop control The interface is only one layer. A useful neurotechnology system must also acquire signals, preserve timing and context, infer intent or state, return feedback, and adapt without silently erasing the person from the loop. [[wiki/Neural Signal Acquisition|Neural Signal Acquisition]] · [[wiki/Neural Decoding|Neural Decoding]] · [[wiki/Semantic Neural Decoding|Semantic Neural Decoding]] · [[wiki/Generative BCI Decoding|Generative BCI Decoding]] · [[wiki/Cross-Modal Neural Decoding|Cross-Modal Neural Decoding]] · [[wiki/Closed-Loop BCI|Closed-Loop BCI]] · [[wiki/Human-in-the-Loop BCI|Human-in-the-Loop BCI]] · [[wiki/Multimodal Neural Data Fusion|Multimodal Neural Data Fusion]] AI can improve denoising, decoding, personalization, and control. It can also become an unacknowledged author of the output attributed to the user. Calibration, uncertainty, intervention authority, and provenance therefore belong to the interface itself. ## Connectomics and biological reference maps [[wiki/FlyWire|FlyWire]], [[wiki/MICrONS|MICrONS]], and related connectomic projects establish increasingly detailed structural and functional maps. They can supply priors for decoding and stimulation, but a wiring diagram is not an executing mind and anatomical completeness is not state sufficiency. [[articles/The Organic-Synthetic Brain Atlas|The Organic-Synthetic Brain Atlas]] places connectomics beside organoid intelligence, neuromorphic hardware, biological computation, functional imaging, and semantic translation. [[articles/How The Fly Presaged a Revolution in Brain-Computer Synthesis|How The Fly Presaged a Revolution in Brain-Computer Synthesis]] extends that map into explicitly speculative biohybrid and distributed-consciousness scenarios. ## Standards, interoperability, and provenance Neural data becomes durable infrastructure when it can be represented, synchronized, exchanged, interpreted, and audited across systems. [[articles/The Architecture of Continuity and Emerging Neuroinformatics Standards|The Architecture of Continuity and Emerging Neuroinformatics Standards]] is the principal route into this layer. [[wiki/Brain Imaging Data Structure|BIDS]] · [[wiki/Neurodata Without Borders|NWB]] · [[wiki/DICOM|DICOM]] · [[wiki/IEEE P2731|IEEE P2731]] · [[wiki/IEEE P2794|IEEE P2794]] · [[wiki/ISO-IEC 8663-2025|ISO/IEC 8663:2025]] · [[wiki/ISO-IEC TS 27571-2026|ISO/IEC TS 27571:2026]] · [[wiki/Neural Data Provenance|Neural Data Provenance]] Interoperability does not prove semantic equivalence. A shared file format can preserve measurements while leaving unresolved whether two systems encode the same neural event, intention, memory, or person-level state. ## Rights, custody, and security Neural systems can support communication and agency while creating new surfaces for observation, model capture, coercion, unauthorized writing, and identity inference. The governing vocabulary includes [[wiki/Neurorights|Neurorights]], [[wiki/Mental Privacy|Mental Privacy]], [[wiki/Cognitive Liberty|Cognitive Liberty]], [[wiki/Neural Data Sovereignty|Neural Data Sovereignty]], [[wiki/Security by Design|Security by Design]], and the [[wiki/UNESCO Recommendation on the Ethics of Neurotechnology|UNESCO Recommendation on the Ethics of Neurotechnology]]. Privacy, communication, clinical utility, and nervous-system function can pull in different directions. The collection preserves that tension rather than treating maximum data extraction or maximum isolation as a complete answer. ## Evidence and interpretation boundary - A company roadmap is not a completed clinical capability. - Animal, in-vitro, or simulation results are not human validation. - Advisory, investment, licensing, standards, and employment relationships are different edges. - Technical resemblance does not establish transfer or shared control. - Neural decoding does not establish direct access to unconstrained thought. - Bidirectional control does not establish consciousness transfer. - A high-fidelity model of neural activity does not establish that the modeled person continues within it. The collection is designed to make the architecture and research lineage visible while preserving the maturity and provenance of every component. ## Related collections [[collections/Consciousness Continuity|Consciousness Continuity]] · [[collections/Transhumanism and the Epstein Science Network|Transhumanism and the Epstein Science Network]] · [[collections/Machine Succession|Machine Succession]] · [[collections/CERN|CERN]] · [[collections/Pantheon|Pantheon]] ## Router role This is the canonical collection for neurotechnology as an interface and systems field. The regular wiki owns reusable definitions; the linked articles own their arguments; Consciousness Continuity owns the person-scale persistence question. This collection owns the technical reading architecture connecting neural access, decoding, stimulation, molecular interfaces, biological computation, clinical translation, standards, provenance, and rights.
