Brain is not fully mature until 30s and 40s

There is a lot of debate about how much the brain changes after our early adulthood. The strengths world suggest that it is pretty much fixed and that success is best achieved by building on those things that are already strengths for us enhancing existing neural pathways, whilst evidence from neuroplasticity indicates that the brain can undergo quite radical changes if we put sufficient effort into the change. In an interesting addition to the debate Professor Sarah-Jayne Blakemore, a neuroscientist with the Institute of Cognitive Neuroscience at University College London says that brain scans show the prefrontal cortex (responsible for high cognitive functions) continues to change shape as people reach their 30s and up to their late 40s.
