Modern science understands very little about that squishy organ that sits betwixt your ears. Neurologists and neurobiologists will try to tell you otherwise, but the fact of the matter is that we understand very little about the brain beyond the most rudimentary level.
For example, it stands to reason that a person with congenital blindness would be incapable of painting, or at least, painting anything beyond the most basic of recognizable shapes. Yet there is Esref Armagan, a congenitally blind painter with artistic skill that would be impressive for even the normally sighted.
Most interestingly, when Esref was hooked up to one of those trendy fMRI (Functional Magnetic Resonance Imaging) chambers and asked to draw, it was found that his visual cortex lit up as if he was actually seeing. This flies in the face of everything modern science knows about neural and cognitive development. Mother nature just keeps throwing curve balls.
