title: Electric times in olfaction.
abstract: Recent work established the spread of interglomerular excitation in the Drosophila antennal lobe. Two papers in this issue of Neuron, by Huang et al. and Yaksi and Wilson, show that cholinergic krasavietz local interneurons are a major substrate for this spread of excitation, predominantly via electrical coupling.
