Figure 6

Central complex of Campodea augens. A) Horizontal section showing the protocerebral bridge (pb, on one side indicated by dashed line) and the central body (cb). Tracts (asterisk) extending through the pb form a chiasma (arrow) before entering the cb columns. mb1: mushroom body 1. amp: anterio-median protocerebral neuropil (dashed line). B) TK-like ir is observed in a middle layer (asterisk) of the central body. Arrow: mb1 Red: TK, green: phalloidin, blue: DAPI. C) AS-like ir present predominantly in a posterior and an anterior layer of the central body (asterisks). Red: AS, green: phalloidin, blue: DAPI. D) Tentative diagram of the central body connectivity. Tracts (t[x]) passing through the protocerebral bridge supply the cenctral body median column (0) and lateral columns (1 to 4). tn: tangential neurons E) RFamide-like ir in the central body. Note neurites innervating the columns from their anterior face (arrow). Scale bars: D: 25 μm, others: 20 μm.
