Figure 4From: Invertebrate neurophylogeny: suggested terms and definitions for a neuroanatomical glossaryThe central complex assembly. A. Schematic representation of the insect central complex compared to B. an original staining of the corresponding neuropils in the brain of the cockroach Periplaneta americana. [Frontal section, double-labeling showing allatostatin-like immunoreactivity (red) and tachykinin-like imunoreactivity (green).] C. The neuropils of the central complex in the malacostracan Spelaeogriphus lepidops correspond to those in insects, but the protocerebral bridge is split. Unlike in insects, the neurite bundles keep ipsilateral between protocerebral bridge and central body. [Frontal semi-thin section. Methylene-blue staining.] Abbreviations: cb = central body; col n = columnar neurons; lal = lateral accessory lobes; pb = protocerebral bridge; tan n = tangential neurons. Originals: A: C.M.
