Figure 6

The tritocerebrum. (A) UV-autofluorescence of antenna 2 and the tip showing the last two antennal segments and fl bearing the ao (inset). (B) AnN as revealed in anti-5HT and anti-SYN labeling. Parts of A2Nv enter the neuropil in a groove like depression (double arrowhead, compare with D). The AnN shows traces of repetitively arranged neurite bundles crossing the neuropil in a perpendicular manner (dotted circles). (C,D′) The TNv projects into the AnN posteriolaterally while parts of the A2Nv bypass the neuropil anterodorsally and the target domains in the posterior parts of the neuropil. SYNir illustrates the microglomerular organization of the AnN (inset C). (D) Nerves emerging from A2Nv target muscles at the base of antenna 2 (arrowheads). Parts of A2Nv enter the neuropil in a groove like depression (double arrowhead). (E) Anterior part of the VNC showing two commissures connecting the oc. An anterior vC giving rise to LNv and the posterior MdC.
