Several areas of the brain are associated with memory. The hippocampus, a librarian of sorts, integrates new information into short-term memory and maintains long-term memories within the cerebral cortex. The amygdala processes memories of emotion. Experts say it takes approximately eight seconds of focused concentration to route information through the hippocampus into the correct memory center. Exercising your brain helps stimulate new pathways among brain cells. Word games and puzzles are good, but challenging yourself with new activities is even better. Learn to play chess, the piano-or read a book about something you know nothing about. The more you challenge your brain to do things new and differently, the better. Take a different route home from work. If you're right-handed, brush your teeth or write with your left hand and vice versa. Physical activity is just as important. It increases blood flow throughout your body-and your brain. 30 minutes of aerobic activity a day, or an equivalent amount of brisk walking, gardening or doing housework, is key. Being active socially is a great way to combine physical and mental challenges, such as golfing, dancing or meeting for a Tai Chi class. Another memory-boosting tip is called "chunking," which involves partitioning large amounts of information into easily digestible bites. For instance, you can remember phone numbers in groups of 3, 3, and 4, or think of your grocery list according to sections of the store. Certain foods may boost your brainpower, too. A recent study looked at wild blueberry juice and found it improved the learning and memory of older adults and feeding your brain with antioxidant-rich vegetables, dark-skinned fruits, cold-water fish and nuts also helped.
