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
Colour-sided Colour-sided Colour-sided is a colour pattern of domesticated cattle. It is sometimes called lineback It consists of a dark body colour, with white finching along the spine, white under the belly, and often white also over the tail, head and legs. The ears, nose and feet are generally dark. The pattern may occur in many breeds, but some breeds are consistently colour-sided, including English Longhorn cattle, Irish Moiled cattle, Randall cattle, Riggit Galloway cattle and Lineback cattle. The dark colour may be any solid colour such as black, red or brindle. An extreme pale form of the colour-sided pattern is
