From: Neurons of self-defence: neuronal innervation of the exocrine defence glands in stick insects
Tracing preparations from S. sipylus with neurons innervating the defence gland via the intersegmental nerve complex (N. posterior SOG and N. anterior T1) in a the suboesophageal ganglion and (b–d) the prothoracic ganglion. In the preparations in dorsal view (a–b, d), the left nerves were filled. Prothoracic dorsal neurons located posterior in the ganglion are DUM neurons with bilaterally symmetrical neurites, see arrows in (b, d). c Lateral view of the prothoracic ganglion reveals two DUM neuron somata in the dorsal ganglion in close contact. A further prothoracic neuron occurs located at the dorsal midline (d). The neurite runs medially (white arrowhead) in the ganglion. Nerves in the ganglia were traced using neurobiotin solution. Abbreviations: SOG, suboesophageal ganglion; T1, prothoracic ganglion. Scale bars: 100 μm
