Dr. Karl Pribram discovered (in his early career while studying at Yale) that when monkeys receive visual impressions through their optic nerves (like humans do), the information doesn’t go directly to the visual cortex in the brain. Instead, the information is first filtered through other areas of the brain where it is edited and modified by the monkey’s temporal lobes before it actually reaches its final destination.
Since then, numerous studies have been performed on human beings that confirm the belief that our own “processing” and “editing” of the “raw image” occurs in a similar way. In a nut shell, “what we see isn’t always what we get”.
Some studies suggest that 50%! of what we “see” is not based on the information that is entering our eyes, but pieced together out of our expectations of what the world should look like. We are so used to responding to what we think is there, that we don’t always see what is really there.
Although, moment by moment, we take in fresh evidence of our surroundings from our visual organs, it’s really the brain that sees. This might explain how someone is able to look in a field where a UFO has landed and mistake it for a round greenhouse….
