Neuralink Corporation is a neurotechnology company founded by Elon Musk and others, developing implantable brain–machine interfaces (BMIs). The company's headquarters is in San Francisco; it was started 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 read 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 2021.
Some claims made by Musk in relation to the technology have been criticized by several neuroscientists and publications, including the MIT Technology Review.
