Technologies that link the brain directly to computers or devices, via implanted or external sensors, for medical restoration and neural research.
Casey Harrell, who has ALS, has communicated nearly 2 million words through a brain implant, his team reported in Nature Medicine. The record is one patient's, and the researchers Science News quotes expect others to follow.
Reality
Science Corporation has implanted its PRIMA retinal chip in its first Stargardt disease patient, CEO Max Hodak announced at TechCrunch Disrupt. Only one participant's early rehabilitation has been reported so far, so this is a feasibility step for the extension.

Bridge Neurotech launched with $13.5 million to build a non-surgical ultrasound brain-computer interface, aimed at people who will not accept a brain implant. The device trades the fast, direct neural signal that lets implant users move robotic arms and type for a slower reading taken from blood flow.
Reality
Precision Neuroscience raised $250 million at just over a $1 billion valuation, $42.5 million of it from Bill Ackman's Pershing Square and his institute. The other $207.5 million came in undisclosed amounts, so the round names its generalist investors without showing what they paid.
Reality
BrainGate researchers found motor cortex firing in two people with tetraplegia was strongest for a photorealistic hand and weakest for an abstract cube. The ordering bears on how assistive devices are shaped, though nobody was controlling anything during the recordings.
Reality
The neural value alignment work with Microsoft Research Asia decodes brain waves to tell an agent whether its goal or its method was wrong. The speed claim comes from simulations.
Reality
United Imaging and Tianjin University say uMR Shenguan decodes, modulates and measures in one system. The specifications that would let anyone check that are not in the announcement.

Neko Health's consumer scan data would reportedly pre-screen candidates for Neuralink's PRIME trial. The interesting part is not the science, it is what the consent form has to cover.
