Examples of activated OSN identification and counting.

All photographs shown are confocal optical sections. (AC) Overviews of 9 dpf larval zebrafish cross-sections triple-stained for DAPI, S100 and pERK. (A'-A'''), (B'-B'''), and (C-C''') show magnified monochromatic pictures of each marker in the olfactory epithelium. Note examples of activated crypt cells in imprinted larvae tested with kin odor (A-A''') as well as some mOSNs and cOSNs (B-B'''). In non-imprinted larvae tested with kin odor, crypt cells are not activated (C-C'''). (D) shows a DAPI view of the position of the olfactory epithelium relative to eye and olfactory bulb with a corresponding explanatory drawing. Larval brain outline indicates the level of section of (D). Drawing at right bottom gives an overview on the cytoarchitectonic organization of the olfactory epithelium.
