I like to ask about stimulating brain by light (similar to Optogenetics) non surgical way by combinations of effectiveness of brain stimulation by light and none surgical stimulating brain methods.
i have seen this post :
which is used to newer infrared blue light to penetrating to brain skull and amplified by some nano chemical martial injected to the mouse brain .
so i found this light wavelength could penetrate:
the Near-infrared light (NIR) has shown promise in animal models of both TBI and stroke. ... Our recent tissue studies demonstrate no penetration of low level NIR energy through 2 mm of skin or 3 cm of skull and brain. However, at 10–15 W, 0.45%–2.90% of 810 nm light penetrated 3 cm of tissue.
and this chart:
so could this penetrating be sorted to stimulating as surgical Optogenetics usages at brain.
so what SE sites are proper to ask this question?
