Neuralink Corporation is an American neurotechnology company founded by Elon Musk and others, developing implantable brain–machine interfaces (BMIs). The company's headquarters are in San Francisco;[5] it was started in 2016 and was first publicly reported in March 2017.[1][2]

Since its founding, the company has hired several high-profile neuroscientists from various universities.[6] By July 2019, it had received $158 million in funding (of which $100 million from Musk) and was employing a staff of 90 employees.[7] At that time, Neuralink announced that it was working on a "sewing machine-like" device capable of implanting very thin threads into the brain, demonstrated a system that read information from a lab rat via 1500 electrodes (said to be 15 times more than the current maximum for systems used in human brains), and anticipated to start experiments with humans in 2020.[7]

Company overview[edit]

Neuralink was founded in 2016 by Elon Musk, Ben Rapoport, Dongjin Seo, Max Hodak, Paul Merolla, Philip Sabes, Tim Gardner, Tim Hanson, and Vanessa Tolosa.[5]

In April 2017, a blog called Wait But Why reported that the company aims to make devices to treat serious brain diseases in the short-term, with the eventual goal of human enhancement, sometimes called transhumanism.[8][5][9] Musk said he got partly interested in the idea from a science fiction concept called "neural lace" that is part of the fictional universe in The Culture, a series of 10 novels by Iain M. Banks.[9][10]

Musk defined the neural lace as a "digital layer above the cortex" that would not necessarily imply extensive surgical insertion but ideally an implant through a vein or artery.[11] Musk explained that the long-term goal is to achieve "symbiosis with artificial intelligence",[12] which Musk perceives as an existential threat to humanity if it goes unchecked.[12][13] At the present time, some neuroprosthetics can interpret brain signals and allow disabled people to control their prosthetic arms and legs. Musk aims to link that technology with implants that, instead of actuating movement, can interface at broadband speed with other types of external software and gadgets.[13]

As of 2018, Neuralink was headquartered in San Francisco's Mission District, sharing an office building with OpenAI, another company co-founded by Musk.[14] Musk was the majority owner of Neuralink as of September 2018, but did not hold an executive position.[15] The role of CEO Jared Birchall, who has also been listed as CFO and president of Neuralink, and as executive of various other companies Musk founded or co-founded, has been described as formal.[16][14] The trademark "Neuralink" was purchased from its previous owners in January 2017.[17]


By 2018, the company had "remained highly secretive about its work since its launch", although public records showed that it had sought to open an animal testing facility in San Francisco; it subsequently started to carry out research at the University of California, Davis.[14]

In July 2019, Neuralink held a live-streamed presentation at the California Academy of Sciences. The proposed future technology involves a module placed outside the head that wirelessly receives information from thin flexible electrode threads embedded in the brain.[18] The system could include "as many as 3,072 electrodes per array distributed across 96 threads" each 4 to 6 μm in width.[18][19] The threads would be embedded by a robotic apparatus that would avoid damaging blood vessels.[18][20]

One engineering challenge is that the brain's chemical environment can cause many plastics to gradually deteriorate.[7] Another challenge to chronic electrode implants is the inflammatory reaction to brain implants.[21][22] Transmission of chemical messengers via neurons is impeded by a barrier-forming glial scar that occurs within weeks after insertion followed by progressive neurodegeneration, attenuating signal sensitivity.[22] Furthermore, the thin electrodes which Neuralink uses, are more likely to break than thicker electrodes, and currently cannot be removed when broken or when rendered useless after glial scar forming.[23] Meanwhile, the electrodes are still too big to record the firing of individual neurons, so they can record only the firing of a group of neurons.[23] This issue might get mitigated algorithmically, but this is computationally expensive and does not produce exact results.[23]
