Also, an EEG device is very useful for quantifying actual brain activity/Alpha-Theta wave frequency/amplitude/ actual meditation performance/progress. See also neurofeedback, some proponents of which have been promising the effects of 40 years of zen meditation in a few tens of NFB sessions.

Do you recommend any particular devices? Muse, etc?

An OpenBCI / OpenEEG and devices from that class (I'm building one myself right now actually, but based on the AD7771 (similar to https://github.com/neuroidss/FreeEEG32/) instead of the TI ADS1299 that OpenBCI uses).

Thank you. I don't have the know-how to build this device myself. Do you know any sites that sell openBCI/EEG devices?
