Colour centre in humans as an area specialized for colour vision. V2, also called the prestriate cortex, is believed to have a small role in colour processing by projecting signals from V1 to the V4-complex. Whether or not colour selective cells are present in V2 is still being investigated. Some optical imaging studies have found small clusters of red-green colour selective cells in V1 and V2, but not any blue-yellow colour selective cells. Other studies have shown that V2 is activated by colour stimuli, but not colour after images.[8] V4 also has feedback on V2, suggesting that there is a defined network
Saxon Colour pigeons Muff (feathered) legged. Saxon Colour pigeons The Saxon Colour pigeons are a group of Saxon breeds of fancy pigeons developed over many years of selective breeding. Saxon Colour pigeons, along with other varieties of domesticated pigeons, are all descendants from the rock pigeon ("Columba livia"). Saxon Colour pigeons are a combination of various varieties which are basically the same type differing only in colour and markings. Some varieties include: "Saxon Breast pigeon", "Saxon Monk" (pictured), "Saxon Priest", "Saxon Reversewing", "Saxon Shield", "Saxon Spot" and "Saxon Whitetail". Saxon Colour pigeons have similar colour varieties to the Thuringian Colour pigeons but the
