[Neuro] Eyes-open EEG stimulation via the ear canals

The initial tests were done in a darkened room with no external interference, sound or otherwise.  The light pipes are optically isolated from the photic stimulation setup to prevent any EMI influence with the EEG electrodes, for that very reason.

I'd also recommend a test where the light source is placed in the ear
and activated, but with a cover in place to block all light, to make
sure that the observed effect is not electronic interference.

Coupling a three channel light pipe assembly to the output stage of a conventional photic stimulation system, in an isolated setting I can empirically show strong brainwave stimulation and entrainment in at least three major cortexes without implicating the visual cortex and without the use of binaural beats.
