I hope you find what you are are looking for, just remember that the brain is a virtual brain in a virtual body, as Jim said it is part of the camouflage reality. And so any exterior tools we use to look at / measure the material reality (other than our own inner senses) are again virtual tools in a virtual reality, as they are part of the camouflage, whatever we use to observe or measure what we are looking for will not influence and/or change what we observe.
So I would say be open to the wave of possibility and look within yourself, rather than outside yourself, but of course keep learning all you can with whatever resources you have available to you.
EDIT: A further note (and feel free to disagree or explore other options). From my point of view, the mind is not in the brain, nor is it even contained to just the physical body. However, if we look for evidence of a particular belief, rather than to explore without pre-conceptions - then we will no doubt create evidence that confirms our already held belief.
so the Q then becomes, am I looking for evidence of my belief, or to go beyond the belief itself into new territory where the specific answers I want may not exist?
I have run into this issue many times with the Seth material, and again trust my inner self to guide to something that makes sense to me, in whatever form is satisfying.
