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 seed oil studied for its potential to treat inflammatory disorders, arthritis, atopic eczema, and respiratory inflammation. In herbal medicine, borage seed oil has been used for skin disorders such as eczema, seborrheic dermatitis, and neurodermatitis; it has also been used for rheumatoid arthritis, stress, premenstrual syndrome, diabetes, attention deficit-hyperactivity disorder (ADHD), acute respiratory distress syndrome (ARDS), alcoholism, pain and swelling (inflammation), and for preventing heart disease and stroke. There is insufficient scientific evidence to determine the effectiveness of borage for a majority of these uses. Several clinical studies have shown it to be ineffective at treating atopic eczema. Its efficacy to treat
