Cover legend: This image shows a bipolar sensory neuron (red) and an identified motor neuron (blue) in the stomatogastric ganglion of the crab, Cancer borealis, labeled with intrasomatic fluorescent dye injection. The axon of the sensory neuron sprouts several neurites that branch off the main axon trunk and make putative synaptic contacts with the motor neuron. For more information, see the article by Städele and Stein. (pages 6718–6731).
