title: Learning: the good, the bad, and the fly.
abstract: Olfactory memories can be very good-your mother's baking-or very bad-your father's cooking. We go through life forming these different associations with the smells we encounter. But what makes one association pleasant and another repulsive? Work in deep areas of the Drosophila brain has revealed the beginnings of an answer, as reported in this issue of Neuron by Owald et al. (2015).
