That’s a great story about the Monolith.

To answer your question: My primary goal right now is simply reliable, high fidelity data collection. However, I think neurofeedback is a fascinating application. I’ve been interested in eventually mixing this tech with tACS in a closed loop control system to train the brain to enter specific mental states.

Regarding the MonolithEEG, it's wild to look back at that tech. It is a shame it was limited to 2 channels at 10 bit resolution, but it was a pioneer. With the ADS1299, we are now getting 24 bit resolution across 8 channels. That difference in dynamic range makes a huge difference, especially for precision applications like SSVEP where the noise floor really matters.

Congratulations on pushing the envelope on open source EEG tech!

Also, for more context:

  Transcranial alternating current stimulation (tACS) is a unique form of non-invasive brain stimulation.
