I don't think kernel has demonstrated fast optical imaging of direct neuronal activity here. The article clearly mentions they detect oxygen activity corresponding, like conventional fNIRS or fMRI.

I've been looking at this field and my conclusion was that non-invasive optical imaging of direct neuronal activity, while possible in theory, it requires several magnitudes of improvement in today's technology. Even Openwater is detecting blood flow (and not individual neurons). Wrote my thoughts here: https://notes.invertedpassion.com/Consciousness/Fast+optical...

Curious to hear what you were building and whether you actually got close to doing fast optical imaging. Happy to chat offline, my email is here: https://invertedpassion.com/about/
