Yeah. So it does the signal processing to kind of really compress the amount of signal that you're recording. So we have a total of thousand electrodes, um, sampling at, uh, you know, just under 20 kilohertz with 10 bit each. So, uh, that's 200 megabits, um, that's coming through to the chip, uh, from thousand, uh, channel simultaneous, uh, neural recording. And that's quite a bit of data.

and you know there is there are technology available to send that off wirelessly but being able to do that in a very very thermally constrained environment that is a brain so there has to be some amount of compression that happens to send off only the interesting data that you need which in in this particular case for motor decoding is

occurrence of a spike or not, and then being able to use that to decode the intended cursor movement. So the implant itself processes it, figures out whether a spike happened or not with our spike detection algorithm, and then sends it off, packages it, sends it off through Bluetooth

to an external device that then has the model to decode, okay, based on these spiking inputs, did Nolan wish to go up, down, left, right, or click, or right click, or whatever?

Yeah, there's an external charging device. So yeah, the second part of the implant, the threads are the ones, again, just the last... three to five millimeters are the ones that are actually penetrating the cortex. Uh, rest of it is actually most of the volume is occupied by the battery, uh, rechargeable battery. Um, and, uh, you know, it's about a size of a quarter.

Uh, you know, I actually have a device here. If you want to take a look at it, um, you know, this is the flexible thread component of it. And this is the implant. So it's about a size of a US quarter. It's about nine millimeter thick.

So basically this implant, once you have the craniectomy and the durectomy, threads are inserted and the hole that you created, this craniectomy, gets replaced with that. So basically that thing plugs that hole and you can screw in these self-drilling cranial screws to hold it in place.

And at the end of the day, once you have the skin flap over, there's only about two to three millimeters that's obviously transitioning off of the top of the implant to where the screws are. And that's the minor bump that you have.
