Investing in the Brain

This month’s cover story looks at optogenetics, a field of neuroscience helping to advance our understanding of the differences between the healthy and diseased brain. As the world population ages, knowledge of neurodegenerative diseases is becoming increasingly important. Countries around the world are investing large sums of money to develop new technologies toward a lifelong healthy brain—but much more is needed.
