Neural Interface

# Neural Interface **Entity class:** Technology, method, or technical system **Domain:** Neurotechnology / Bioengineering **Doc Type:** Concept Node **Maturity:** Evolving **Related:** [[Brain-Computer Interfaces]], [[Neural Signal Acquisition]], [[Neural Decoding]], [[Closed-Loop BCI]] --- ## Definition A **neural interface** is a technical boundary through which a system records from, stimulates, modulates, or exchanges information with neural tissue. The category includes interfaces whose primary purpose is clinical measurement, assistive control, therapeutic stimulation, communication, or experimental investigation. ## Architectural role The term is broader than BCI. A BCI emphasizes a functional communication pathway between brain activity and computation; a neural interface also includes component technologies that acquire or stimulate signals without yet constituting a complete user-facing control loop. ## Simple Reminders, Quotations, and Thoughts  > "When we talk mathematics, we may be discussing a secondary language built on the primary language of the nervous system." > **— John von Neumann**, *The Computer and the Brain / related remarks; source verification pending* *Verification Status: Unverified — exact wording/source has not yet been independently confirmed against a primary source; source clue: The Computer and the Brain / related remarks; source verification pending.* [[reminders/unverified/Mathematics May Be a Language Built on the Nervous System by John von Neumann|Mathematics May Be a Language Built on the Nervous System by John von Neumann]] > "The human operator and the equipment will be intimately coupled." > **— J.

Never mind fields like optogenetics, which alter and reconnect our brains, thoughts, memories, fears using light stimuli projected inside the brain. Eventual implants will radically change brain design, inputs, and outputs. Having a baseline, a good paleoneurological history of brain design, for ourselves and many other basic species, may teach us a lot about what our brains were, where they came from, but even more important, what they are becoming. I bet this is a challenge Tilly Edinger would have relished." > **— Juan Enriquez**, *2017, Edge Annual Question, “What Scientific Term or Concept Ought to Be More Widely Known?”* [[reminders/Neural Interfaces/Brain Implants Will Change What Our Brains Are Becoming by Juan Enriquez|Brain Implants Will Change What Our Brains Are Becoming by Juan Enriquez]] > "I've argued elsewhere that the neural code may turn out to be so complex that it will never be fully deciphered. But 60 years ago, some biologists feared the genetic code was too complex to crack. Then in 1953 Crick and Watson unraveled the structure of DNA, and researchers quickly established that the double helix mediates an astonishingly simple genetic code governing the heredity of all organisms. Science's success in deciphering the genetic code, which has culminated in the Human Genome Project, has been widely acclaimed — and with good reason, because knowledge of our genetic makeup could allow us to reshape our innate nature. A solution to the neural code could give us much greater, more direct control over ourselves than mere genetic manipulation." > **— John Horgan**, *2006, Edge Annual Question, “What Is Your Dangerous Idea?”* [[reminders/Neural Interfaces/Solving the Neural Code Could Give Us Direct Control Over Ourselves by John Horgan|Solving the Neural Code Could Give Us Direct Control Over Ourselves by John Horgan]] > "A second, more futuristic solution may lie in technology. Brain-computer interfaces are already around the corner. They are currently being developed for therapeutic purposes. Soon, cortical implants will allow paralyzed patients to move equipment by direct cerebral command. Will such devices later be applied to the normal human brain, in the hopes of extending our memory span or the speed of our access to information? And will we be able to forge a society in which such tools do not lead to further divisions between, on the one hand, high-tech brains powered by the best education and neuro-gear, and on the other hand, low-tech man power just good enough for cheap jobs?" > **— Stanislas Dehaene**, *2006, Edge Annual Question, “What Is Your Dangerous Idea?”* [[reminders/Neural Interfaces/Brain Interfaces May Divide Humanity Into High-Tech and Low-Tech Minds by Stanislas Dehaene|Brain Interfaces May Divide Humanity Into High-Tech and Low-Tech Minds by Stanislas Dehaene]] > "What does this have to do with consciousness? Instead of focusing on pedantic philosophical issues, Crick and Koch began with their naïve intuitions. "Consciousness" has many attributes—continuity in time, a sense of agency or free will, recursiveness or "self-awareness," etc. But one attribute that stands out is subjective unity: you experience all your diverse sense impressions, thoughts, willed actions and memories as being a unity—not jittery or fragmented. This attribute of consciousness, with the accompanying sense of the immediate "present" or "here and now," is so obvious that we don't usually think about it; we regard it as axiomatic." > **— Vilayanur Ramachandran**, *2012, Edge Annual Question, “What Is Your Favorite Deep, Elegant, or Beautiful Explanation?”* [[reminders/Consciousness/Consciousness Unifies What the Brain Keeps Distributed by Vilayanur Ramachandran|Consciousness Unifies What the Brain Keeps Distributed by Vilayanur Ramachandran]] > "Efforts to change the way we think—and to enhance our cognitive capacity—are ancient. Brain enhancers come in several varieties. They can be either hardware or software, and they can be either internal or external to our bodies. External hardware includes things like cave paintings, written documents, eyeglasses, wristwatches, wearable computers, or brain-controlled machines. Internal hardware includes things like mind-altering substances, cochlear implants, or intra-cranial electrical stimulation. Internal software includes things like education, meditation, mnemonics, and cognitive therapy. And external software includes things like calendars, voting systems, search engines, and the Internet." > **— Nicholas A.

Christakis|Human Enhancement Has Always Included External Tools by Nicholas A.

The invention of fire, of the wheel, of antibiotics or the Internet changed how we live our lives in profound ways. It made our lives safer, more comfortable, and more exciting. But they have not changed who we are. Being able to record and manipulate brain activity will change who we are. It will serve as an interface through which computers can become part of our brain, and through which our brains could directly interface with each other." > **— Christian Keysers**, *2016, Edge Annual Question, “What Do You Consider the Most Interesting Recent Scientific News?

Electrodes implanted into the memory centers of the patient's brain reported spikes in response to the photos. One of the neurons responded vigorously to several pictures of Jennifer Aniston, but not to other famous people. A neuron in another patient would only respond to pictures of Halle Berry, and even to her name, but not to pictures of Bill Clinton or Julia Roberts or the names of other famous people.” > **— Terrence J.

About two billion years ago mitochondria evolved from primitive bacteria by entering into a symbiotic relationship with early eukaryotic cells. Each benefitted the other; so this was not a hostile takeover but a gradual coming together until neither the living cells nor the mitochondria within them could survive without the other. The cells feed and protect the mitochondria; they provide the power. Could our future be heading this way? The analogy implies a world in which humans manage the power supplies to feed an ever-increasing number of inventions in return for more fun, games, information and communications; a world in which we so value the fruits of our machines that we willingly merge both physically and mentally with them.” > **— Susan Blackmore**, *2013, Edge Annual Question, “What *should* We Be Worried About?”* [[reminders/Neural Interfaces/Humans May Merge with Machines as Cells Merged with Mitochondria by Susan Blackmore|Humans May Merge with Machines as Cells Merged with Mitochondria by Susan Blackmore]] > “The same neural machinery that enables us (if we so choose) to imagine the emotional or physical pain suffered by another also allows us to predict how our current choices will influence our future selves. This is known as prospection. But humans are also lazy; we make choices now that we come to regret later. (I’m guilty of that right now: rather than actually building our future robot overlords, I’m daydreaming about them instead.) Machines could help us here too. Imagine neural implants that can directly stimulate the pain and pleasure centers of the brain. Such a device could make you feel sick before your first bite into that bacon cheeseburger rather than after you’ve finished it. A passive aggressive comment to a colleague or loved one would result in an immediate fillip to the inside of the skull.” > **— Joshua Bongard**, *2016, Edge Annual Question, “What Do You Consider The Most Interesting Recent [Scientific] News? What Makes It Important?”* [[reminders/Neural Interfaces/Neural Implants Could Make Future Consequences Felt Now by Joshua Bongard|Neural Implants Could Make Future Consequences Felt Now by Joshua Bongard]] > “Already tens of thousands of people have cochlear implants with direct electronic to neural connections to restore their hearing. Multiple groups are working on retinal implants, either into the eyeball, or interfacing to V1 at the back of the head; again to replace lost capabilities such as those resulting from macular degeneration. A few quadraplegics have direct neural connections to computer interfaces so that they can control a mouse and even type. As progress is made with these silicon/neural interfaces, pushed along by clinical pressures to cure those who are impaired, we can expect more and more "plastic surgery" applications. A direct neural typing interface first perhaps, and later data going the other way directly from the network into our brains. There are considerable challenges to be met in understanding neural "coding" to do this, but the clinical imperative is pushing this work along.” > **— Rodney A. Brooks**, *2002, Edge Annual Question, “What Is Your Question? ... Why?”* [[reminders/Neural Interfaces/Neural Implants Will Become Part of Everyday Life by Rodney A. Brooks|Neural Implants Will Become Part of Everyday Life by Rodney A. Brooks]] > “The basic cellphone has morphed into a powerful, mobile, multimedia communication device and computer terminal that is a major driver of Internet society. It gives immediate, constant contact with select, distant conversants, and can tell you where you are, where you should go next, how to get there, provide diversions while waiting, and document your journey with text, snaps and video images. For some, this is enhanced reality, but it comes at the price of the here-and-now. Whatever your opinion and level of engagement, the cellphone and related Internet devices are profound social prostheses — almost brain implants — that have changed our lives and culture.” > **— Robert Provine**, *2010, Edge Annual Question, “How Is The Internet Changing The Way You Think?”* [[reminders/Neural Interfaces/The Cellphone Has Become a Social Prosthesis and Almost a Brain Implant by Robert Provine|The Cellphone Has Become a Social Prosthesis and Almost a Brain Implant by Robert Provine]] > “Twenty or thirty years ago, people dreamed of a global mind that knew everything and could answer any question. In those early times, we imagined that we'd need a huge breakthrough in artificial intelligence to make the global mind work — we thought of it as resembling an extremely smart person. The conventional Hollywood image for the global mind's interface was a talking head on a wall-sized screen.” > **— Rudy Rucker**, *2010, Edge Annual Question, “How Is The Internet Changing The Way You Think?”* [[reminders/AI Control/The Global Mind Emerged Without a Breakthrough in AI by Rudy Rucker|The Global Mind Emerged Without a Breakthrough in AI by Rudy Rucker]] > “The development of mind-reading technology is in its infancy, of course. But reliable lie-detection will be much easier to achieve than accurate mind reading. Whether on not we ever crack the neural code, enabling us to download a person’s private thoughts, memories, and perceptions without distortion, we will almost surely be able to determine, to a moral certainty, whether a person is representing his thoughts, memories, and perceptions honestly in conversation. Compared to many of the other hypothetical breakthroughs put forward in response to this year’s Edge question, the development of a true lie-detector would represent a very modest advance over what is currently possible through neuroimaging. Once this technology arrives, it will change (almost) everything.” > **— Sam Harris**, *2009, Edge Annual Question, “What Will Change Everything?”* [[reminders/Neural Interfaces/True Lie Detection by Sam Harris|True Lie Detection by Sam Harris]] > “Can we create new senses for humans—not just touch, taste, vision, hearing, smell, but totally novel qualia for which we don't yet have words?” > **— David M.

For one thing, our relationship to computers will be completely and irrevocably altered; clumsy input devices like mice, windows, keyboards, and even heads-up displays and speech recognizers will go the way of typewriters and fountain pens; our connection to computers will be far more direct. Education, too, will fundamentally change, as engineers and cognitive sciences begin to leverage an understanding of brain code into ways of directly uploading information into the brain. Knowledge will become far cheaper than it already has become in the Internet era; with luck and wisdom, we as species could advance immeasurably.” > **— Gary Marcus**, *2009, Edge Annual Question, “WHAT WILL CHANGE EVERYTHING?”* [[reminders/Neural Interfaces/Decoding the Brain Could Replace Screens With Direct Information Transfer by Gary Marcus|Decoding the Brain Could Replace Screens With Direct Information Transfer by Gary Marcus]] > “How will the advent of direct brain-to-brain communication change the way we think?” > **— Thalia Wheatley**, *2018, Edge Annual Question, “WHAT IS THE LAST QUESTION?”* [[reminders/Neural Interfaces/How Will Brain-to-Brain Communication Change Thought by Thalia Wheatley|How Will Brain-to-Brain Communication Change Thought by Thalia Wheatley]] > “How will advances in mental prosthetics that connect us with other human and machine minds change the way we think about expertise?” > **— Tania Lombrozo**, *2018, Edge Annual Question, “WHAT IS THE LAST QUESTION?”* [[reminders/Neural Interfaces/Will Mental Prosthetics Connect Human and Machine Minds by Tania Lombrozo|Will Mental Prosthetics Connect Human and Machine Minds by Tania Lombrozo]] > “Another set of opportunities and responsibilities will arise when radiotelepathy is extended from humans to other animal species.

Collection route: [[collections/Neurotech|Neurotech]]. - **INF-0031 — Plausible.** Every molecular interface requires a delivery vector, which makes AAV capsid engineering an interface technology rather than a gene-therapy technology. Capsid tropism determines which cells can be addressed, so the vector library is functionally the addressing scheme of the future nervous-system network.  ## Research Inference Attractors  These are secondary semantic placements for the inference attractor network.

A population of untethered sensors addressed acoustically scales with acoustic focusing precision rather than with surgical access, and that is a different curve entirely. - **Canonical cluster:** [[wiki/Neural Interfaces and Continuity Architecture|Neural Interfaces and Continuity Architecture]] - **INF-0015 — Strongly indicated.** Read bandwidth has advanced far ahead of write bandwidth, and continuity requires both. A system that can record a state but not install one supports observation, not transfer, which makes patterned stimulation the decisive unsolved half of the uploading stack. - **Canonical cluster:** [[wiki/Neural Interfaces and Continuity Architecture|Neural Interfaces and Continuity Architecture]] - **INF-0023 — Plausible.** Below roughly a hundred milliseconds, a decoded action stops feeling like operating a tool and starts feeling like moving. Sub-perceptual latency is the threshold at which the interface is incorporated into the body schema, and body-schema incorporation is the psychological precondition for substrate transfer. - **Canonical cluster:** [[wiki/Neural Interfaces and Continuity Architecture|Neural Interfaces and Continuity Architecture]] - **INF-0034 — Plausible.** A one-time sensitizing edit followed by a lifetime of external field addressing inverts the economics of neural interfacing: the expensive, risky step happens once and the hardware upgrades stay outside the body. This is the configuration most likely to reach populations rather than patients. - **Canonical cluster:** [[wiki/molecular neural interfaces|molecular neural interfaces]] - **INF-0038 — Analytic.** Acoustoelectric sensing uses ultrasound to tag the location of electrical activity, recovering spatial precision from a diffuse electrical measurement. It is the only current approach that promises electrode-grade localization with no electrode, and British state research funding is upstream of it. - **Canonical cluster:** [[wiki/molecular neural interfaces|molecular neural interfaces]] - **INF-0041 — Analytic.** A sensitized cell population is a permanent modification even when the hardware is external, which relocates the irreversibility from the device to the genome. Consent frameworks written for implants do not describe this situation, and the gap will be discovered clinically before it is described legally. - **Canonical cluster:** [[wiki/molecular neural interfaces|molecular neural interfaces]] - **INF-0047 — Strongly indicated.** The peripheral nervous system is accessible without craniotomy and carries organ-regulatory traffic, which makes it the first place where continuous closed-loop control of the body's internal state becomes routine. Central interfaces will inherit a control theory developed peripherally. - **Canonical cluster:** [[wiki/molecular neural interfaces|molecular neural interfaces]]
