Trouble getting any actual signals
Some background info:
- New ganglion board and electrodes
- Dry comb electrodes paired with Headset kit
- MacOS
I've followed the headset tutorial, instead only having one electrode at the O1 region. Impedance of electrode got around ~220kohm as lowest. No matter what I seem to try, it appears as though the time series is just displaying noise with very high rms. Where should I go from here?

Comments
In this case, I think the electrode is not making good contact with the skin. Also, the reference impedance is low but not great, so it may not be making great contact either.
