    Notes: Summary Immunofluorescent staining for glial fibrillary acidic protein (GFAP) has been used as part of the diagnostic evaluation of eleven patients and compared with routine special stains. In one case, a difficult fibrillary neoplasm of the spinal cord, this diagnostic procedure provided rapid, positive identification of the glial nature of the tumor. In all cases, the GFAP reactivity was consistent with staining properties of PTAH and more rapid than PTAH.

    Notes: Abstract We studied the association between honey bee (Apis mellifera) division of labor and performance on an olfactory reversal-learning test. Manipulations of colony age structure and flight experience were used to test whether differences in performance are associated with age, current behavioral state, or flight experience. Nurse bees showed significantly faster rates of extinction to a learned odor than did foragers. This difference was associated primarily with differences in behavioral state, rather than age; it was seen when comparing nurses and foragers from typical colonies and normal-age nurses and precocious foragers from single-cohort colonies. Differences in extinction rate were not related to differences in flight experience; there was no difference between foragers and foraging-age bees denied flight experience. These results suggest that changes in learning and memory occur in association with division of labor. We speculate on the possible functional significance of the difference in extinction rate between nurses and foragers.
