Making Memories

Science Daily: Making memories stronger and more precise during aging - New mechanisms by which new neurons sharpen memories

summary - Buried deep underneath the folds of the cerebral cortex, neural stem cells in the hippocampus continue to generate new neurons, inciting a struggle between new and old as the new attempts to gain a foothold in memory-forming center of the brain. Researchers have found they can bias competition in favor of newly generated neurons. Results may have implications for PTSD, MCI, and age-related memory loss.
