a-d: Representative images showing FMRP immunoreactivity in the intact (a) and afferent-deprived NMs at 48 hours (b), 96 hours (c), and 1–2 weeks/7–14days (d). Dashed lines outline the border of the NM. a1-d1: High-magnification view of the boxes in a-d, respectively. e-g: Frequency histograms of z-scores of FMRP immunoreactivity in the intact and afferent-deprived NM neurons. Abbreviations: d, day; h, hour; NM, nucleus magnocellularis; OD, optical density. Scale bars = 50 μm in a (applies to a-c); 10 μm in a1 (applies to a1-d1).
