"I don't get tired. I think a part of the issue is that I just want to stay up all the time," Arbaugh said.
Arbaugh, who is quadriplegic, made the comment in response to a question about whether the implanted device makes him tired.
Arbaugh pointed out that he recently ended up using the device for more than 17 hours.
"The other day, I couldn't sleep so I decided to hop on at around 2:00 a.m. and I ended up using it all day," he said.
Arbaugh noted that he spends about four hours per day, Monday through Friday, with Neuralink’s team in structured sessions.
In addition, Arbaugh said he can spend another six hours on the device outside of the official meetings for personal use.
