Fig. 8From: Neurons of self-defence: neuronal innervation of the exocrine defence glands in stick insectsDistribution of neurons in the suboesophageal (top row) and prothoracic ganglion (bottom row) revealed by retrograde tracing of the left N. anterior SOG in a P. schultei, b S. sipylus, c C. morosus, and d E. tiaratum. Ganglia are shown in dorsal (top) view after filling of the left N. anterior SOG. The nerves in all original ganglia preparations were traced using neurobiotin solution as tracer. Abbreviations: CLN, contralateral neuron; ILN, ispilateral neuron; N. a., Nervus anterior SOG; PIN, prothoracic neuron; VMN, ventral median neurons. All scale bars: 100 μmBack to article page
