Neuronal architecture in NA following injections to different sites, all transverse sections. A: Labeled auditory nerve terminals reveal the glomerular organization of NA, after injection of CTX into auditory nerve. B: Retrogradely labeled NA neurons after injection of FITC-DA into contralateral torus semicircularis. C: Retrogradely labeled NA neurons after NB injection into the ipsilateral SOd. Inset: NA neurons. D: Retrogradely labeled NA neurons after NB injection into contralateral SOd. Inset shows NA neurons. E: Retrogradely labeled NA neurons after injection of NB into the contralateral SOv. F: Schematic drawing to show labeled neuronal distribution: neurons projecting to TS marked by circles, neurons projecting to SOd marked with asterisks, and neurons projecting to contralateral SOv with triangles. Scale bars = 200 μm in A,B; 50 μm in C–E; 500 μm in F; 20 μm in inset C; 10 μm in inset D. [Color figure can be viewed in the online issue, which is available at wileyonlinelibrary.com.]
