ALL IN THE FAMILY A neural stem cell (green) in a mouse’s memory-related hippocampus produces new cells over the course of two months. Red cells are newborn neurons, and orange and yellow are slightly older cells produced by the stem cell.

Brain scientists have filmed a first-of-a-kind birth video.

It reveals specialized cells in the brains of mice dividing to create newborn nerve cells.

The images, published in the Feb. 9 Science, show intricacies of how certain parts of the adult mouse brain can churn out new nerve cells. These details may help lead to a deeper understanding of the role of this nerve cell renewal in such processes as memory.

Deep in the brains of mice, a memory-related structure called the hippocampus is…
