Re: EEG While Meditating

Hi Rohan,

I couldn't see much of a motion artifact from the breathing as evidenced by
the first minute of normal breathing and the first few seconds of
Kapalabhati. I do, however, have a strong suspicion that a change in skin
conductance (GSR) might be causing some artifacts. I wanted to record in
parallel with my LightStone IOM, but the GSR sensor is broken. Perhaps a dry
electrode would work better.

But there is no denying the subjective experience of increased electrical
potential that feels just like the spikes on the printout if you perform the
breathing exercise as instructed.

Kind regards,
Michael.

Hi Michael,

Interesting work. Do you find you have motion artifact during the breathing?

Cheers,
Rohan
