• "It turns out that there are numerous chemical growth factors, including several that act in the nervous system, where they are known as neurotrophins."
• "But there's also a number of these proteins or molecules called neurotrophins, and some of them are produced in the brain, such as the brain- derived neurotrophin factor or BDNF, and some of them are produced in the periphery, such as IGF1 or insulin-like growth factor 1 produced in the muscles and other regions of the periphery."
• "These neurotrophins also influence the process of neuroplasticity, controlling where new nerve branches go, pruning the old, unused ones, and deciding which neurons to connect with others in a neural circuit.15"
