How Many Nurons Are There?

Ray Kurzweil: How many neurons, what kind of resolution? I think on one good, one, good thing here to think, is to split it up into a few categories. So maybe i'll start with sort of about how many nurons we can get with what spatial precision. Then diserothlab group, who has blown out how wide you can go. And then ean should jump in here with temporal precision, because i think his paper is the one that really slammed donks that. These are all in sort of different quadrants. You can't do all these things simultaneously. It's almost as easy as buying a bigger lazer.

Episode notes

Welcome back to Neurotech Pub!

This episode is part two of a two part series on optical methods for recording and stimulating neural activity. Our guests on this episode are Elizabeth Hillman, PhD, Mark Schnitzer, PhD, and Jacob Robinson, PhD. Last time we talked about optical recording methods, but in this episode we focus on optical stimulation methods.

Cheers!
