"Precision Neuroscience has unveiled information about the "Layer 7 Cortical Interface" brain implant, which is thinner than a human hair. The new technology will allow paralysis patients to control digital devices using only neural signals.

The interface is an array of electrodes that resembles a piece of tape and is thinner than a human hair, allowing it to adhere to the surface of the brain without damaging tissue. Embedded technology decodes brain signals and translates them into commands for external technology.

While the Neurolink implant is designed to be implanted directly into brain tissue, the Precision Neuroscience implant is based on a surgical technique designed to be less invasive. To implant the Layer 7 Cortical Interface Array, the surgeon makes a very thin incision in the skull and inserts the device like a letter in a mailbox.

The nature of the procedure allows Precision Neuroscience to easily increase the number of electrodes in the array, which Meijer says will eventually allow the Layer 7 Cortical Interface to be used not only for paralysis treatment but also for neurological purposes. The procedure is also reversible if patients decide they no longer need the implant or want new versions in the future. The developers have successfully used their device to decode neural signals in animals; the scientists hope to receive FDA approval to test the technology in humans by mid-2023.
