One of the earliest explanations was that of retinal function by which the retina itself projects in a certain direction only the image received upon it, and is connected by one particular nerve fiber with the brain in such a way that the brain connection of the upper retinal element lies below, that of the lower above, that of the right to the left and of the left to the right, so that the image is reinverted
