A marvelous book, lucid and informative. Human eyes do not make a pixel grid image in the brain - they convert signals from 120 million receptors into 1 million information-compressed neural signals, representing color and contrast and edge differences. The signals split left and right, crossing over at the optic chiasm, pass through the lateral geniculate nucleus (LGN, the author has no explanation for this) and converge on the anterior striate cortex at the back of the brain. Some of the pre-LGN axons split off to drive the left and right lobes of the superior colliculus, which is involved in eye tracking.
