Summary

Neurons in the brains of birds change their responses as the birds hear a birdsong over and over again. This “learning” persists and is then forgotten, but in a surprising report by Chew et al. (p. 1909) in this week's issue of Science, it is shown to disappear not in a gradual way over time but in a series of quantized steps. In her Perspective, Doupe comments on the implications of this result.
