sNPFR immunoreactive cluster c9 is only detected in the posterior lateral protocerebrum of mediums and minors (posterior view).

Abstract

<p>(A) Schematic representation of the location of c5 (central) and c9 (lateral). Images in the top panel show the right hemisphere and the bottom images, the left one. In minor worker brains cluster c9 is detected near the optic lobe, symmetrically on both sides of the brain (B, G). Also, c9 is present in medium worker brains (C, H). In majors, cluster c9 is undetectable (D, I). No fluorescent signal was observed in negative controls, with pre-immune serum (E, F) or antigen-preabsorbed antibodies (J). Lo: lobula.</p
