So sieht es im Operationssaal aus, wenn jemand ein Gehirnimplantat bekommt

Precision is a three-year-old startup building a brain-computer interface, or a BCI. A BCI is a system that decodes neural signals and translates them into commands for external technologies. Perhaps the best-known company in the field is Neuralink, which is owned by [Tesla](https://www.cnbc.com/quotes/TSLA/) and SpaceX CEO [Elon Musk](https://www.cnbc.com/elon-musk/).

Other companies like Synchron and Paradromics have also developed BCI systems, though their goals and designs all vary. The first application of Precision’s system will be to help patients with severe paralysis restore functions like speech and movement, according to its website.

Precision’s flagship BCI is called the Layer 7 Cortical Interface. It’s a microelectrode array that’s thinner than a human hair, and it resembles a piece of yellow scotch tape. Each array is made up of 1,024 electrodes, and Precision says it can conform to the brain’s surface without damaging any tissue.

When Bederson used four of the company’s arrays during the surgery in April, he set a record for the highest number of electrodes to be placed on the brain in real-time, according to Precision. But perhaps more importantly, the arrays were able to detect signals from the patient’s individual fingers, which is a far greater amount of detail than standard electrodes are able to capture.
