Also, the claim is not that deficient magno cells are causing difficulty in mathematics. It was just a manifestation of the theory that inefficient perception is correlated with learning difficulty. The test could have easily been performed with dyslexics or kids with motor control problems instead of with math tests – they are just inherently easier to score and measure. However, I think much further study is indeed needed to try and bridge visual perception inefficeincy with specific learning deficits and correlate that information with actual brain function abnormality.

The eyes have only added another variable to an already immensely complex equation.
