absolutely. In terms of sight and pixels... Our eyes are like the scanner or camera. It takes a snapshot of the surroundings and sends it to the brain. If we had the capability, the brain would be able to zoom in on something - but it doesn't necessarily make it more clear. It's just like taking an image and zooming in on a spot of the picture. You don't see any more detail than you did before. The 'pixels' just get larger. The only way for our brains to see images more clearly is if we got closer to the object, or our eyes took a better quality picture. Our brains are not 'programmed' to filter out colors, but that is something the brain could do. The brain customizes a lot of things. For example, an eskimo could go outside on a snowy day here in AR and not feel nearly as cold as somebody from the equator. Part of the reason is a body more suited to keeping themselves warm - but it is also cause the brain is accustomed to colder temperatures than what the eskimo is feeling. Another example is pain. Many times the brain filters out pain messages when it needs to. The brain can discard or pay special attention to any particular aspect of a sense.
