Fig. 1. Schematic representation of the stomatogastric nervous system (STNS) of Pugettia producta, including the locations (blue stippling) of putative synaptic neuropils, as indicated by the presence of synapsin-like immunoreactivity, within the STNS. coc, circumesophageal connective, CoG, commissural ganglion; dpon, dorso-posterior esophageal nerve; dvn, dorsal ventricular nerve; ion, inferior esophageal nerve; lvn, lateral ventricular nerve; mvn, medial ventricular nerve; OG, esophageal ganglion; on, esophageal nerve; pdn, pyloric dilator nerve; son, superior esophageal nerve; STG, stomatogastric ganglion; stn, stomatogastric nerve; vlvn, ventro-lateral ventricular nerve.
