Additional Benefits of Exercise on Memory

A neuroscientist says there’s a powerful benefit to exercise that is rarely discussed

But my favorite neuroscience-based motivation for exercise relates to its effects on the hippocampus—a key brain structure that’s critical for long-term memory. We all have two hippocampi: one on the right side of the brain and the other on the left. The hippocampus is unique because it is one of only two brain areas where new brain cells continue to be generated throughout our lives, a process called adult hippocampal neurogenesis.

Studies in rodents demonstrated that increased levels of physical exercise can result in improved memory by enhancing both the birth rate and the survival of new hippocampal brain cells. Exercise encourages the long-term growth of hippocampal cells by immediately increasing levels of a key growth factor in the hippocampus called Brain Derived Neurotrophic Factor (BDNF. Now, when I exercise, I imagine BDNF levels surging in my hippocampi, encouraging all those new hippocampal cells to grow.

...Recent findings have suggested that the brain’s hippocampus is also involved in giving people the ability to imagine new situations. Since we know that exercise enhances the birth of new hippocampal brain cells and can improve memory function, this discovery suggests that exercise might be able to improve the imaginative functions of the hippocampus as well.

Do you exercise, and have you found it beneficial for cognitive ability? I eat a very healthy diet, but I need to increase my exercise levels.
