Fig. 3. Amvl expression in the honey bee brain. Antennal lobes (AL); Kenyon cells (KC); subesophageal ganglion (SOG). (A) Anterior coronal section, which includes the antennal lobes. Squares delineate regions shown magnified. (B) Posterior coronal section, which includes the SOG. No labeling was seen in control sections probed with a sense riboprobe (C). There were no obvious spatial differences in expression patterns between nurses and either forager type (N=3 brains per group); these images are from a pollen forager brain. Brains were sectioned from the anterior (AL) to the posterior end (SOG).
