Hey everyone, about 10 days ago I gave a presentation to NeuroTechX on my progress, it begins at the 1:29:00ish mark.
On the 9th at about the hour mark one of the leading researchers on EROS gave a presentation. EROS is basically an HEG but with a thousand fiber optic sensors that can fully reconstruct the outer inch or so of your brain in 3D, with parity to fMRI imaging. I recommend that presentation too!
Here's the next week's presentation with the talk by Kyle Mathewson (at about the 55:00 mark) who worked on EROS and is performing all kinds of wizardry with his colleagues in Canada. This is like an HEG on steroids, with parity to fMRI imaging for the outer cortex.
