Neuralink’s competitor just tested the brain’s transplantation in someone

The computer’s computer interface Startup Paradromics announced today that the surgeons have successfully introduced the company’s brain transplant in a patient and to remove it safely after about 10 minutes.

It is a step towards longer experiences of the device, called Connexus. It is also the latest business development in a growing field of companies – including Elon Musk’s Neuralink– Claiming to connect people’s brains directly with computers.

With Connexus, Austin -based Paradromics is looking to restore speech and communicate in people with spinal cord injury, stroke, or atrophic side sclerosis, also known as Als. The device is designed to translate nerve signals into speech, text and control of the index. Paradromics, founded in 2015, tests her transplantation in sheep over the past few years. This is the first time that the device is used in a human patient.

The procedure occurred on May 14 at the University of Michigan and was performed in a person who was undergoing brain surgery to treat epilepsy. The patient gave their approval to incomplete the Connexus device in the temporal lobe, which treats hearing information and codes memory. To plant the device, surgeons use an Epipeen -like tool developed by PHADROMics. The researchers then managed to verify that the device was able to record electrical signals from the patient’s brain.

“There is a very unique opportunity when someone undergoes major neurological surgery,” says Matt Angel, CEO of Physiclycs. “Their skull will be opened, and there will be a piece of brain that will be removed in an unlimited way. In these conditions, the marginal risk of testing the brain transplant is very low.”

Paradromics transplantation is smaller than the size of the dim and has 420 small needles that are pushed into the brain tissue. These needles are poles that record from individual neurons. Likewise, Neuralink cultivation also falls into brain tissue. (Compared, it contains more than 1,000 pole distributed over 64 flexible thin threads.) Other BCI companies follow less troop. Define Neuroscience, for example, tests the transplant Located on the surface of the brainSYNCHron has developed a device It goes in a blood bowl It settles against the brain. Each of this device collects signals from groups of neurons, instead of individualism.

“By proximity to individual neurons, you can get the highest quality sign,” says Angel. Getting a high -resolution signal from the brain is an important thing to decompose the accurate person’s discourse.

BCIS No “Read” the person’s special ideas directly. Instead, they work by interpreting the neurological signals associated with the intention of movement. For example, BCI like surprises that develop, for example, deciphering the parties involved in the talk. A person with paralysis cannot move his mouth to try to make this movement, which produces unique nervous signals in the brain. Then these signs are decoded in speech.

In 2023, groups of Stanford University and Uc San Francisco were mentioned The main developments in deciphering speech using BCIS. In two women with paralysis, the brain transplant was able to decode the intended speech at 62 and 78 words per minute. For comparison, people speak about 130 words per minute.
