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

Yes, and heavier than air flying machines were once impossible as well.

Here is one somewhat relevant study published a few months ago that does in fact show that neurons in a primate's brain are activated by blue light:

Can you provide any reason whatsoever why we should believe that the
ear canal is even sensitive to degree of light, let alone color?

Binaural beats are 100% irrelevant to this, as is light stimulation of
the eyes (which, shockingly, *do* contain light receptors).

You're proposing to flash light into someone's *ear*, and claiming
that this will somehow affect their brain. That's simply not possible
without there being some kind of light receptors there, and there are
none.

Also, mind that with EEG you're going to have very high sensitivity to
placebo effect. Any trial that's not fully blinded will not be worth
looking at.

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.
