Do acupuncture points provide better or worse electrode locations for BCI?

One of the studies we did at JPL during the Summer was to investigate the effect of supposed acupuncture nodes on scalp electrode/skin impedance (which may result in unusual EEG readings). We could only do a limited number of measurements due to the limitations of the equipment we had with us.

Lois Clark (a student) volunteered to be the subject of the tests. Below is the motage we were able to put together. It places 6 electrodes approximately 1cm apart in the area of a well-known acupuncture point.

We found nothing significant (albeit with one participant only), but a larger study will be run in the future before the hypothesis can be ruled out.
