Fig. 4. BDNF and trkB mRNA localization in the brainstem. Sections were hybridized with BDNF or trkB antisense riboprobes, a: Darkfield
photomicrograph of the brainstem demonstrates BDNF mRNA in the vestibuloauditory nuclei at the level of entry of the eighth nerve• DO,
dorsal (auditory) nucleus; LVN, lateral vestibular nucleus: MVN, medial vestibular nucleus: DVN, descending veslibular nucleus. Scale
bar = 140 lam. b: Darkfield photomicrograph of the brainstem at the level of the eighth nerve root displays trkB hybridization in cells (arrows)
of the lateral vestibular nuclei. Scale bar= 140 I-tm. |
