Laburnum anagyroides plant contain cytisine and are poisonous if consumed. The wood is hard and heavy, of a yellow/brown colour, ideal for making posts, for woodturning and as fuel. In the past (and today on historic re-enactments) it was used for making bows. The tree is also known as "false ebony" since the wood from very old specimens could be used in place of ebony. "Laburnum anagyroides" is cultivated as an ornamental tree. The most common ornamental plant in the genus is a hybrid between this species and "Laburnum alpinum" — Laburnum × watereri. The English poet Francis Thompson described the "laburnum"
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.
