The butterfly effect

« Does the flap of a butterfly’s wings in Brazil set off a tornado in Texas? » wondered the meteorologist Edward Lorenz in 1972. Small events can indeed act as catalysts and cause major impacts on a complex system. In the complex structure of the brain, the « heart » of this butterfly effect is the choroid plexus. This epithelial tissue, present in each of the ventricles of our brain, produces the cerebrospinal fluid on a daily basis and synthesizes important molecules necessary for proper brain functions. What makes the heart beat is engraved in the memory…
