Bypass fibers, the protocerebral bridge neuropil and the central body neuropil showing allatostatin-like immunoreactivity (AST; green). A: Inverted single channel picture of a horizontal vibratome section, allatostatin-like (AST; black) immunoreactivity in higher magnifications from Fig. 3A. The arrows identify possibly related fibers, bypassing the protocerebral tract and showing clear ASTir. B: Inverted single channel picture of a horizontal vibratome section, allatostatin-like (AST; black) immunoreactivity in the protocerebral bridge neuropil (PB) and the central body neuropil (CB) in higher magnifications from Fig. 4C. C: A silver impregnation of a microtome slice is shown in a similar section plane and higher magnification. Asterisks label several identifiable fiber bundles connecting the PB with the CB. Other abbreviations: AMPN, anterior medial protocerebral neuropil HN, hemiellipsoid neuropil; TM, terminal medulla.
