If what you say is true that brains fill in things for us, where is the evidence that something is stored in the brain. There is no evidence the brain stores anything. That is the spirit filling in for us.
It's true. Every human being has a blind spot - the spot on our retina where the optic nerve connects doesn't contain any light-sensitive photoreceptor cells and so we are blind in that part of our field of vision. We don't notice this spot where we actually can't see anything because our brains, along with the information from our other eye, fill in the missing parts of our field of vision with what it thinks should be there. This is demonstrable and verifiable.
I'm not sure why you don't think things are stored in the brain but we know that episodic memories, for example, are stored in the hippocampus.
You really should brush up on what we know about the human brain if you're going to be making these kinds of definitive statements.
I would recommend "The Brain That Changes Itself" by Norman Doidge to start.
If a person is blind in one eye they lose depth perception. I am not sure what the missing bits are.
The blindness in this case was actually caused by a lesion on the visual cortex within the brain. The patient had experienced a stroke which had caused the lesion. Her vision was fine before the stroke, so her brain had ample experience with binocular vision for her entire life up to that point. For months after her stroke she had no idea that she actually could not see out of her left eye, because her brain (with the help of her right eye and with it's previous encounters with the environment) was filling in what it thought should be there. It was only after her doctor noticed something particular about the way she was interacting with her environment that she suspected the patient wasn't actually viewing what was in front of her. Then she had a person sit to the left of the patient, in her periphery, (and without telling the patient) and asked the patient if she could see him. Turns out she couldn't. It turned out that if she knew the person was there, she could see them. But if she was not told the person was there, she could not see him. Now clearly, memory must be stored in the brain or her brain wouldn't have the memory to fill in the blanks for her.
I can't remember the name of the book at the moment but I will try to come up with it and let you know. It's pretty fascinating, really.
I am not saying the brain is unremarkable, I am saying it is the interface between spirit and body.
You kind of are. You keep trying to attribute functions of the brain to spirits and spirit worlds when it isn't necessary. When we already have actual explanations with actual explanatory power for these things.
I think the video showed very clearly the NDE was not physical. There are many more on YouTube and the Net.
I didn't see any disembodied minds floating around. Did you?
