I am not sure.. I have absolutely no training specific to neurology, so I probably could not say for sure, but apparently it is a portion of the brain that is not exactly cortex.. and apparently it has been measured and found to be a non-growing portion.. In any event (Sorry- I truly do not have a source for this, lol) perception is real and always differs between any two people in existence, even if only based on where they stand in a room, relative to how they might see that room and the images that they perceive from that position.. (Someone by the door, looking in- obviously perceives the room in the sense of being "from the doorway"- and "outside looking in"- and say the other person is in the room- then the person seeing it from the doorway looking in, also sees it as having a person inside, or being occupied. The person already in the room would quite probably see it as the inside of a room, and void of another person other than herself, and may consider the room to be unoccupied.. And just seeing things visually differently- seeing a couch from the back, versus the front, etc.. It is not that the lack of adequate perceptive ability we humans have necessarily changes significantly anything we see as normal or mundane- but there are always going to be fundamental differences in how we see those things, therefore we have a lacking in ability to be able to broadly imagine or perceive something that we have not yet had the capacity to picture..
You could imagine what the front of the couch looks like, seeing it from the back, if you have seen any couch before, or if you have (better yet) seen the front of this particular couch before. But, say the front of the couch has a cat laying on it.. You cant see the cat from behind the couch.. You have to change your perception to do that. Its is not possible to perceive a cat on the couch, if you do not know what a cat is, or a couch is.. You would certainly see the couch and the cat, even if it was for the first time ever in your life seeing such things as couches or cats- lol- and you would see and perceive its color and dimensions and everything that a person who has had plenty of experiences with couches and cats can perceive seeing- the same dimensions, and the same cat tail flicking back and forth, lol.. But you just cant imagine a cat you have never heard of, or seen, without being properly introduced to it in concept, at least- and you would never know it was even a cat at all, without seeing a photo of it, or being able to have some way of connecting it to whatever you were told a cat IS.. And the best verbal description of a dog, without describing a cat, can still lead a person who has never before seen a...uh.. cat OR a dog, to believe that the animal on the couch is actually a dog- with the furry ears, tail, and furry body- four legs, etc..
OK So when I am describing these events in perception, I am referring to God as a belief that can be perceived in ways that do not always coincide with other's beliefs of who or what God is, also.. And I am just saying.. That's perfectly okay and normal.
