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

It's not that the ear canals are sensitive to light or have receptors,
it's that the light can hit brain tissue directly through the ear
canal.

A quick search for "ears sensitive to bright light" brings up a lot of
results, such as
http://www.prnewswire.com/news-releases/the-human-brain-is-sensitive-to-light-breakthrough-findings-from-valkee-and-the-university-of-oulu-127506878.html
and some hear-and-there articles about clinical trials using bright
light shined inside of ears to treat SAD.

That's all I have to say. I'll let you decide whether or not to delve deeper.

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.
