I really appreciate your time in reading my post and giving a well thought out comment. Let me preface my response with the fact that I am only a part-time neurologist As such I employ everyone to do their own research to keep me honest…

It is important to understand that although gravity is a factor in the movement of blood volume during head movement, it is not necessarily a draining effect that moves the blood. Simple inertia resulting from gravity also works to keep the blood “still” while the head moves “around it”. Take auditory access for instance, the head is simply moving from side to side and as such there is no draining of blood, only “movement” to parts such as the Broca’s area.

With respect to experiencing and processing light, the information that we receive is based on frequency and regardless of the angle that the light is presented to the retina (unless it is out of peripheral vision) the frequency doesn’t not change. As such, the information is processed and disseminated according to that frequency (for instance a blue shirt against a white wall presents different frequencies at their intersection and the “difference” is the root of what is processed). It is not the eyes necessarily that channel the light (meaning the lens) but the retinal wall and the optic nerve that are at first responsible for (at a course level) filtering and channeling the information to the visual thalamus (which shoots rough information directly to the amygdala for immediate fight/flight processing) and then along to the visual cortex (for finer processing and dissemination along to the prefrontal cortex [complete processing] and medial temporal lobe [memory development]).

If you are really interested in finding out more, I implore you to do some in depth research. I would be very interested to hear more from your findings. Thanks again for commenting and please keep in touch.

I found your articles on Eye Accessing Cues quite interesting.

Particularly the paragraph on: “Where ever the eyes go, the head and then eventually the body follows. So the eyes moving upward is mainly for the purpose of helping to tilt the head back and increase gravitational blood flow to the visual cortex. ”

This is interesting but not necessarily accurate. Since the part of the brain responsible for physical sensation is at the top of the head, it doesn’t hold that looking down brings greater blood flow to the area.

One hypothesis that came to me but that I’ve never tested or taken forward is that eye position channels light energy in a certain direction which ends up stimulating specific parts of the brain.

Notice how this might hold:

Sight can be stimulated by gazing forward or up. If you trace a line that goes from line of sight into the brain, you’ll land on the visual cortex.

Sound can be stimulated by looking laterally. Take a look on a brain map where the auditory cortex is found: right on the sides.

If someone looks down and you trace a line from line of sight into the brain, you’ll land right on the part responsible for physical sensation.

Might light be responsible for stimulating the brain? Might the eyes be the lenses that channel light to specific parts of the brain?

What do you think?
