Cover picture: Laser-scanning confocal image of a male antennal lobe of the moth, Manduca sexta. Olfactory receptor neuron axons, which are labeled for nitric oxide synthase (green) are closely apposed to the processes of large subsets of intrinsic antennal lobe neurons, which are labeled for nitric oxidesensitive soluble guanylyl cyclase (red). For details, see the article by Collmann et al. in this issue (pages 6070–6077).
