How life shapes the brainscape

摘要

Our brains form a million new connections for every second of our lives. It is a mind-blowing statistic, and one that highlights the amazing flexibility of our most enigmatic organ. While the figure emphasises how much we still have to learn about brain structure, it also reveals the huge importance of our everyday experiences in making our brains what they are. Anatomy, neural networks and genes are yesterday's hot topics. Today, neuroscientists are increasingly concentrating on how the way we live our lives creates profound and often long-lasting changes in the structure and connectivity of our brains. They are focusing on how influences as diverse as our emotions, environment, social interactions and even our spiritual lives help make us tick.
