Elon Musk said the second Neuralink implant had on the order of 400 electrodes providing signals.
“we've got, um, I think, on the order of 400 electrodes that are are providing signals.”

Elon Musk said Neuralink hoped to implant ten people in total by the end of the year, subject to regulatory approval.
“so we're hoping to do ten by the end of this year, total of ten, so eight more.”

The Neuralink N1 implant has 64 threads with 16 electrodes each, for 1,024 electrodes that can both record and stimulate.
“the current instantiation of the device has 64 threads, and each thread has 16 electrodes for a total of 1024 electrodes that are capable of both recording and stimulating.”

DJ Seo said the implant's charging must not raise surrounding brain tissue temperature by two degrees Celsius, a strict regulatory limit.
“There is a very strict regulation and good reasons to not actually increase the surrounding tissue temperature by two degrees Celsius.”

DJ Seo said Neuralink's surgery takes two to four hours from patient in to patient out, and about three and a half hours for Noland Arbaugh.
“we say patient in to patient out is anywhere between two to four hours. Uh, in particular case for Nolan, it was about three and a half hours.”

Neuralink recovered Noland Arbaugh's performance after thread retraction by adding spike band power output alongside its BOSS spike-detection algorithm.
“So once we kinda changed the algorithm for the implant to not just give you the boss output, but also these, uh, spike band power output.”

Matthew MacDougall said Neuralink's first human implant surgery was done with the Barrow Neurologic Institute.
“we're lucky to have just incredible partners at the Barrow Neurologic Institute. They are, uh, I think, the premier neurosurgical hospital in the world.”

Bliss Chapman said Neuralink's end-to-end latency from brain spike to cursor movement was about 22 milliseconds.
“our end-to-end latency right now, from brain spike to cursor movement, is about twenty two milliseconds.”

Matthew MacDougall said deep brain stimulation surgery is accepted to cause a brain bleed in about one in a hundred patients, a rate that Neuralink wants to beat dramatically.
“it's accepted with this approach that there's gonna be about one in a hundred patients who have a a bleed somewhere in the brain”
