Abstract
From a small flat image projected on the retina of each eye, our brain is able to reconstruct a three-dimensional reality, one in which the objects of the physical world are perceived in depth, and whose positions are judged faithfully, coinciding almost perfectly with their real space coordinates. From those two flat squared images, our brain invents a rich reality, full of details, colors and hues. A seemingly simple process requires, notwithstanding, the contribution of a constellation of complex, and so far, mysterious, cognitive routines, algorithms that nature has discovered over millions of years of evolution. In this article we will make a fast and modest journey through the extraordinary world of our visual system, and propose a plausible hypothesis that would explain the strange and paradoxical crossing at the midline optic chiasm.© 2015.
