Fig 9. Response profiles and glomerular targets of olfactory receptor neurons (ORNs) from long trichoid sensilla on the antennae of transplant males.

Fig 9

Recordings from V-S transplant males confirmed the presence of sensillar types that are typical for a normal H. virescens antenna. (A-C) Recording from a A-type sensillum housing a Z11-16:Ald ORN (A). Staining revealed projections to the cumulus and PCx1 glomeruli (B, C). (D-F) Recording from a B-type sensillum containing a Z9-14:Ald ORN (D). Staining revealed projections from this sensillum to the dorso-medial glomerulus (DM) and a posterior complex glomerulus (PCx) (E, F). (G-H) Recording from a C-type sensillum containing ORNs responsive to Z11-16:OAc and Z11-16:OH (G). Staining revealed a projection to the antero-medial glomerulus (AM) in this preparation–an observation that is consistent with the normal arborization pattern of ORNs associated with this sensillum type (H). The other paired ORN in the C-type sensillum typically projects to the ventro-medial glomerulus (VM) (but stains of axonal terminals in VM were not seen clearly in this preparation). Some silver-intensified cobalt stains of axon terminals are indicated by small white arrowheads in each section. Scale bar = 100μm (for histological images: B, C, E, F, H); D, dorsal, M, medial–axes the same for each histological image.
