Neuralink is even more speculative - they want to embed like a thousand tiny metal filaments deep into your brain.

Neuralink is even more speculative - they want to embed like a thousand tiny metal filaments deep into your brain.
- 2008guy 7y agoHow do you place electrodes without metal filaments? It’s been validated in monkeys.
- mattkrause 7y agoIs that true? There was a throwaway comment about that at a press conference and lots of rumors (positive and negative), but the white paper only mentions “monkey” once—-and in a reference to another group’s paper.
- 2008guy 7y agoElon musk said on stage that they had put it in a monkey and had the monkey move a cursor with it. I’ve been following musk very closely since 2010 and he’s never blatantly lied so I think this will not be the first time. He has made errors about timelines and etc but never, ever blatantly lied about something so concrete. And it’s plausible to boot.
- erohead 7y ago> never blatantly lied. Funding secured
- mattkrause 7y agoNot to swing my credentials around, but I actually record neural activity, from monkey brains, for a living. It can be unexpectedly hard in so many different ways. The dura covering the monkey brain is much tougher, the brain itself is larger, more convoluted, and moves more, even just from breathing and heartbeats). The animals have busy, clever little fingers, so the interface itself needs to be mechanically robust and durable because these implants need to last for years. I certainly want this to be true: with the exception of neuropixels, electrode technology has been depressingly stagnant. On the other hand, I need to see data before I get too excited and if I did have it, I'd be shouting it from the rooftops.
- bognition 7y agoyou need something that conducts electricity. There are groups that use silicon implants.
- bognition 7y agoThis isn't new at all. Groups have been doing this for decades. Neuralink wants to mass produce the devices.
- mattkrause 7y agoPeople have been recording brain activity for decades, but the scale is very different. Until about 10-15 years ago, most labs were using a handful of electrodes (my PhD work, for example, was done with 1-2 at a time). With cheaper amplifiers, it's become more common to use arrays with ~32-96 electrodes and they're often implanted chronically in the brain. Neuropixels are fairly new and offer ~300 channels (selectable from ~1000). The neuralink thing would increase this another 10-fold.
