Fluorescence micrograph of glyoxylic acid treated buccal ganglia. a: dorsal surface b: ventral surface. The structures shown are B20 – neuron that is similar to B20 neuron in Aplysia[4], CBC – cerebro-buccal connective, ET – esophageal trunks, HBN-heterobuccal nerve, N1a – neuron that is involved in the control of feeding in Helisoma[2], PBN – posterior buccal nerve, VBN – ventral buccal nerve.
