We should also consider the difference between "perceived resolution" vs. "processed resolution". For example, when we told someone we "heard things", it's our brain told us that we "heard things", but it's possible that the brain processed a lot more information but only let the "conscious mind" what the brain thinks of what is necessary. I supposed that's what psychology categorize that as "conscious" vs. "subconscious".
There are human beings that are capable of extraordinary ability such as performing mathematical operations that only a computer could. That means that our brain is capable of things that at least our conscious mind is not aware of. But I am glad I don't have that ability since it would drive me crazy and of course why because I have a computer do that for me.
I've said it before that our body is like a machine. In order to process information, or specifically to be able to localize sound, if anything for the sake of survival, the brain needs to perform "mathematics". Just like some underwater mammals, they can possess "sonar" capability like a man-made submarines, and their brains are made up of the same stuffs as our brains. But I am glad I don't have any "sonar" capabilities since I just want to chill out at the beach and enjoy looking at the hot chics. Lols, that's actually a four sentence paragraph.
