A man who can read letters but not numbers exposes roots of consciousness
Somehow this is not surprising for me, I have heard about experiments related to free-will wherein the brain already made a decision even before the conscious mind became aware of it. Thus putting doubts on our conscious experience of free-will.Also, in terms of problem solving, there are experiments which show that the brain calculates the answers and "presents" the answers later on to the consciousness. It's not like the problems were solved within the scope of consciousness, which is of course contradictory to what we experience. We feel the contradictions because we experience everything through consciousness, i.e. we can't experience things which happen outside realm of consciousness. The brain scans prove in a sense that there is a disconnect (For instance in this article the brain scans showed signals related to seeing faces in the numbers, but the conscious experience was not seeing them).The link between what the brain does, and what we experience  (consciousness) is indeed the hard problem of consciousness.
