Figure 5.

Mushroom bodies of Campodea augens. A) Proximal part of mushroom body 1 (mb1) with intrinsic Kenyon cells (kc). A darkly stained region (asterisk) partially separates the peduncle of mb1 from the neuropil at its base. B) Connection (arrow) of the central body with the lateral accessory lobes (lal), which are in turn connected with the antero-lateral protocerebrum (alp). C) Possible connection of axons passing below mb1 and mb1’ (left arrow; mb1’: branch of mb1 extending to the calyx) and axons of the act2 (antenno-cerebral tract 2, right arrow). D) DC0-like ir (red) and phalloidin staining (green) reveal mb1 and the globular lobe of mb2. E) Detail of mb1. F) Detail of mb2 and its thin peduncle (arrow) which originates from lateral Kenyon cells and closely passes by the calycal glomeruli (asterisk). Scale bars: A, B, E, F: 20 μm, C: 10 μm, D: 50 μm.
