DJ Seo said Luigi Galvani discovered animal electricity in the 1790s using electrodes on a frog leg.
“where, um, the concept of animal electricity, or the fact that body's electric was first discovered by Luigi Galvani.”

DJ Seo said German psychiatrist Hans Berger discovered electroencephalography (EEG) in the 1920s.
“So fast forward many, many years to 1920s, uh, where Hans Berger, who's a German psychiatrist, discovered EEG or electro, uh, encephalography, which is still around.”
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 the rigid Utah array was developed by Richard Norman in 1997 at the University of Utah.
“That's been kind of the innovation from Richard Norman back in 1997. Uh, it's called the Utah array, cause, you know, he was at University of Utah.”
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.”
DJ Seo said Noland Arbaugh set a new world record for the WebGrid cursor task of 8.5 bits per second.
“he's actually just beat the world record yet again last week, um, to eight, five BPS.”
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.”
