Mental computer interface Startup paradoomics today announced that surgeons successfully inserted the company’s brain implant into the patient and safely removed it after about 10 minutes.
This is a step towards long trials of the device, which is dubbed Connexus. It is also the latest commercial development in the growing sector of companies – including Elon Musk’s neuronic – claiming to connect people’s brains directly to the computer.
With Connexus, Paradromics based in Austin is seeking to restore speeches and communication in people with spinal cord injury, stroke, or amyotrophic litter sclerosis, also known as ALS. This device is designed to translate the nerve signal into combined speech, text, and cursor control. Paradromics, which was founded in 2015, has been examining its implants in sheep for the past few years. This is the first time he used the device in a human patient.
The procedure took place on May 14 at Michigan University and was done in a man who was undergoing mental surgery to treat his epilepsy. The patient gave his consent to temporarily enter their temporary lobby, which acts on the information and encoded memory. To apply the device, surgeons used an epideon -like device manufactured by paradox. Researchers then succeeded in confirming that the device was able to record the power signal from the patient’s brain.
“When a major neuro is undergoing a surgical procedure, there is a very unique opportunity,” says Matt Angel, CEO of Paradromics. “They are about to open their scalp, and a piece of brain will be removed immediately. In these situations, the minor risk of testing the brain implant is very low.”
The implant of paradoomics is smaller than the size of a penny and has 420 small sprinkled needles that are pushed into the brain tissues. These needles are electrodes that record from individual neurons. Similarly, the implant of neurlink is also sitting in the brain tissue. (In comparison, it distributes more than 1,000 electrodes into 64 thin, elastic threads.) Other BCI companies are taking less unpleasant perspective. For example, the precision neuro science is testing an implant that is tackled to the brain level, and synchronization has developed a device that goes into the blood tract and is against the brain. Both of these devices collect signals from groups of neurons rather than individual people.
“With close proximity to individual neurons, you can get a high quality signal,” says Angle. It is important to get a high resolution signal from the brain to properly decorate a person’s desired speech.
The BCI does not “read” a person’s private ideas directly. Instead, they work by interpreting the nerve gestures associated with the intention of the movement. A BCI that is developing a paradox, for example, will eliminate the movement of the face involved in talking. A stroke person who cannot move his mouth can still try to make a movement, which produces unique nerve indicators in the brain. After that these gestures are declared in the speech.
In 2023, groups from Stanford University and UC San Francisco reported a major progress in the use of speech using BCIS. In two women suffering from stroke, cerebral employees were able to de -code the desired speech at the rate of 62 and 78 words per minute. Comparison people speak about 130 130 words per minute.
