Effective classification of multitasking motor imagery electroencephalogram (EEG) signals is a way to decode the brain's motor intentions

IT Home reported on August 4 that according to Elon Musk, its brain-computer interface company Neuralink has successfully implanted a second brain-computer interface chip into a human patient. This is another major step forward after the first patient was implanted in January of this year.

IT House noted that Musk shared the news during a podcast episode with Lex Fridman on Friday. During the eight-hour conversation, Musk mentioned that the second implant is currently going well, Musk said: "I don't want to jump to conclusions, but the second implant seems to be going very well." The signal is strong, there are a lot of electrodes, and it works very well. （I don't want to jinx it, but it seems to have gone extremely well with the second implant. So there's a lot of signal, a lot of electrodes. It's working very well）”

The implant is part of Neuralink's PRIME study. The study aims to conduct clinical trials of implant technology in patients with quadriplegia due to spinal cord injury or amyotrophic lateral sclerosis (ALS), with the goal of the implant being to help the patient control an external device, such as a computer mouse, using only their minds.

Neuralink set the participant conditions last year, including no history of implanted devices, no history of epilepsy, no need for MRI, no transcranial magnetic stimulation therapy, etc.

Neuralink implanted a brain-computer interface chip into patient Noland Arbaugh for the first time in January this year, following FDA approval in May last year. After implantation, Arbaugh was able to control the computer mouse with only his mind, rather than relying on his mouth and stylus.

In May of this year, Neuralink received FDA approval to install an implant for a second patient. Musk said last month that more than 1,000 people are expected to have Neuralink chips implanted by 2026.
