Sandrine Thuret studies neurogenesis, or the way adult brains create new nerve cells in the hippocampus — a brain area involved in memory and mood.

Her work asks two big questions: How can we help our healthy brains create new nerve cells throughout our lives, through diet and behavior changes? And how can we study the effects of diseases such as depression and Alzheimer’s on our brains’ ability to grow?

As she explains in this TED Talk, diet is one of the ways of generating new brain cells.
