Summary

In the 24 February issue of Neuron, neuroscientists report that the brains of adult male songbirds can recruit certain kinds of neurons to grow and replace cells that have died. What's more, the experiments suggest that the new neurons are fully functional. But the recruitment is selective; only certain cells have this phoenixlike quality. Researchers now hope to discover what causes that selective recruitment so that they can eventually trigger the growth of all types of neurons.
