Laburnum anagyroides during May and June. "Laburnum anagyroides" blooms in late spring with pea-like, yellow flowers densely packed in pendulous racemes 10–25 cm (4–10 in) long. The flowers are golden yellow, sweet scented, and typically bloom in May. The seeds are legumes with large numbers of black seeds that contain cytisine, an alkaloid extremely poisonous to humans as well as goats and horses, especially when not ripe. However, some wild animals such as hares and deer can feed on them without any problems, and because of this the plant is believed to have magic properties in some regions. All parts of the
Colour centre the recognition of shapes, motion, and colour. V1 has multiple areas that are colour-sensitive, which indicates that colour processing is not limited to one area. According to a paper by Dr Robert Shapley, V1 has an important role in colour perception. fMRI experimental results showed that V1 has two kinds of colour sensitive neurons: single-opponent and double-opponent cells. These cells are integral in the opponent process of interpreting colour signals. Single-opponent neurons respond to large areas of colour. This is advantageous for recognizing large colour scenes and atmospheres. In comparison, double opponent cells respond to patterns, textures, and colour boundaries.
