Rory Noland Biography & Facts

Neuralink Corp. is an American neurotechnology company that has developed, as of 2024, implantable brain–computer interfaces (BCIs), and is based in Fremont, California. Founded by Elon Musk and a team of seven scientists and engineers, Neuralink was launched in 2016 and was first publicly reported in March 2017. Since its founding, the company has hired several high-profile neuroscientists from various universities. By July 2019, it had received $158 million in funding (of which $100 million was from Musk) and was employing a staff of 90 employees. At that time, Neuralink announced that it was working on a "sewing machine-like" device capable of implanting very thin (4 to 6 μm in width) threads into the brain, and demonstrated a system that reads information from a lab rat via 1,500 electrodes. They had anticipated starting experiments with humans in 2020, but have since moved that projection to 2023. As of May 2023, they have been approved for human trials in the United States. The company has faced criticism for a large amount of euthanization of primates that underwent medical trials. Veterinary records of the monkeys showed a number of complications with electrodes being surgically implanted. On January 29, 2024, Musk said that Neuralink had successfully implanted a Neuralink device in a human and that the patient was recovering. This person was Noland Arbaugh, who had been paralyzed from the neck down in a swimming accident. Company History Neuralink was founded in 2016 by Elon Musk and a founding team of seven scientists and engineers. The group of initial hires consisted of experts in areas such as neuroscience, biochemistry and robotics. The trademark "Neuralink" was purchased from its previous owners in January 2017. In April 2017, Neuralink announced that it was aiming to make devices to treat serious brain diseases in the short-term, with the eventual goal of human enhancement, sometimes called transhumanism. Musk had said his interest in the idea partly stemmed from the science fiction concept of "neural lace" in the fictional universe in The Culture, a series of 10 novels by Iain M. Banks. 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. He said the long-term goal is to achieve "symbiosis with artificial intelligence", which he perceives as an existential threat to humanity if it goes unchecked. He believes the device will be "something analogous to a video game, like a saved game situation, where you are able to resume and upload your last state" and "address brain injuries or spinal injuries and make up for whatever lost capacity somebody has with a chip." As of 2020, Neuralink was headquartered in San Francisco's Mission District, sharing the Pioneer building with OpenAI, another company co-founded by Musk. As of 2022, Neuralink's headquarters were in Fremont, California. Jared Birchall, the head of Musk's family office, was listed as CEO, CFO and president of Neuralink in 2018. As of September 2018, Musk was the majority owner of Neuralink but did not hold an executive position. By August 2020, only three of the eight founding scientists remained at the company, according to an article by Stat News which reported that Neuralink had seen "years of internal conflict in which rushed timelines have clashed with the slow and incremental pace of science." In April 2021, Neuralink demonstrated a monkey playing the game "Pong" using the Neuralink implant. While similar technology has existed since 2002, when a research group first demonstrated a monkey moving a computer cursor with neural signals, scientists acknowledged the engineering progress in making the implant wireless and increasing the number of implanted electrodes. In May 2021, co-founder and president Max Hodak announced that he no longer works with the company. Only two of the eight co-founders remained at the company by January 2022. Technology In 2018, Gizmodo reported that Neuralink "remained highly secretive about its work", 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. In 2019, during a live presentation at the California Academy of Sciences, the Neuralink team revealed to the public the technology of the first prototype they had been working on. It is a system that involves ultra-thin probes being inserted into the brain, a neurosurgical robot to perform the operations and a high-density electronic system capable of processing information from neurons. It is based on technology developed at UCSF and UC Berkeley. Probes The probes, composed mostly of polyimide, a biocompatible material, with a thin gold or platinum conductor, are inserted into the brain through an automated process performed by a surgical robot. Each probe consists of an area of wires that contains electrodes capable of locating electrical signals in the brain, and a sensory area where the wire interacts with an electronic system that allows amplification and acquisition of the brain signal. Each probe contains 48 or 96 wires, each of which contains 32 independent electrodes, making a system of up to 3072 electrodes per formation. Robot Neuralink says they have engineered a surgical robot capable of rapidly inserting many flexible probes into the brain, which may avoid the problems of tissue damage and longevity issues associated with larger and more rigid probes. This surgical robot has an insertion head with a 25 μm diameter needle made of tungsten-rhenium designed to attach to the insertion loops, inject individual probes, and penetrate the meninges and cerebral tissue; it is capable of inserting up to six wires (192 electrodes) per minute.A linear motor powers the needle, enabling fast retraction acceleration and varying insertion speeds. A 50-μm tungsten wire that has been bent at the tip and is driven both axially and rotationally makes up the pincher. An imaging stack is also included in the inserter head for needle guidance, real-time insertion viewing, and verification. Electronics Neuralink has developed an application-specific integrated circuit to create a 1,536-channel recording system. This system consists of 256 amplifiers capable of being individually programmed, analog-to-digital converters within the chip and peripheral circuit control to serialize the digitized information obtained. It aims to convert information obtained from neurons into an understandable binary code in order to achieve a greater understanding of brain function and the ability to stimulate these neurons back. With the present technology, Neuralink's electrodes are still too big to record the firing of individual neurons, so they can record only the firing of a group of neurons; Neuralink representatives believe this issue might get mitigated algorithmicall....
