Note that information coming from the upper part of visual space (the green and dark blue bars in the visual target in the lower left part of the view) falls on the lower part of the retina, and ultimately projects to the lingula, the gyrus inferior to the Calcarine Sulcus. Conversely, information from the lower part of visual space (the purple and red bars in the targe) falls on the upper part of the retina, and ultimately projects to the cuneus,the gyrus superior to the Calcarine Sulcus.

The red and dark blue colors are intended to represent the pathway conveying information from the central part of the retina - the macula - to the visual cortex. Note that these pathways terminate most posteriorly in the cortex. The green and purple colors represent the pathway conveying information from the peripheral part of the retina. Note that these pathways terminate more anteriorly in the cortex.

The yellow and light blue colors are best ignored in this view.
