Dear Joerg:
Have not heard much from you for a while, and all of a sudden it looks likeyou have been "very" busy!
Seeing such good data, I must try this Driven Right Leg circuit.
The 500 K is for safety? The C5 causes decreased gain with frequency, C4 causes increased gain with frequency. The right leg impedance affects gain. Do you have to tune these to keep it from oscillating?
A question, where exactly to you put the right leg drive? Do you use paste? It seems your "ground" is the ear lobe? Where were the two input leads connected Cz and what? Please explain.

What is cooledit? How can I get it?
Can you increase the resolution around 10 Hz? There seem to be two frequencies there?

At least it seems possible to detect alpha waves ;-)
(See picture with spectral view of a comEEG alpha feedback session)
After the session starts (marked by 3 times clenching my jaw)
alpha (about 10 Hz ) apparently increased, compared to the pre-session
interval.
