How to Build a Better Brain: The Science of Brain Development

For all the thinking we do with the brain, we rarely think about it. The 3-pound mass of crevices and folds is always out of sight and too often out of mind. But the sooner we start paying attention to our brain, the better. Researchers, who once thought the brain's neural circuitry was hardwired at a young age, have discovered that our brain is pliable and that we can fortify it through nutritional, physical and lifestyle habits throughout our life. And we should. A healthy brain pays major dividends: Emerging research shows that the well-maintained brain is quicker, smarter, more resilient and more adept at stabilizing mood. It's also less forgetful and less prone to age-related decline. The human brain at any age is able to strengthen, deepen and change existing neural connections (a process called neuroplasticity), and to develop new neural cells (called neurogenesis). We can encourage these changes by adopting many of the same lifestyle habits that sustain healthy bodies, from focusing on good nutrition and physical fitness to managing stress. Indeed, the health of the body and the health of the mind are virtually one and the same. Think of the hemispheres of the brain as two cities connected by a network of telephone wires. Now we know there are things you can do to add more wires. With a focus on fitness, good food and stress relief, you can add more wires and help your brain stay strong, healthy and resilient at any age. Here's how you can begin tailoring your choices to maximize your brain's health.
