A study published online this week in Nature finds that mice engineered to produce more new neurons in the hippocampus—a structure involved in learning and memory—are better at discriminating between similar choices. The study adds new evidence for a link between the development of new neurons in the hippocampus and cognitive functions in the brain, and it also suggests how these neurons may affect mood disorders.
