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
Borage use of borage is common in Germany, in the Spanish regions of Aragon and Navarre, in the Greek island of Crete and in the northern Italian region of Liguria. Although often used in soups, one of the better known German borage recipes is the Green Sauce (Grüne Soße) made in Frankfurt.
