Article Title: Muscarinic modulation of M and h currents in gerbil spherical bushy cells
Figure Lengend Snippet: Expression of M1 and M2 muscarinic receptors in gerbil AVCN. (A) Calretinin (CR) staining in a parasagittal slice of gerbil cochlear nucleus. The filled arrows point to strong calretinin staining corresponding to big auditory nerve fiber terminals, the endbulb of Held. Scale: 100 μm. (B) M1 muscarinic staining was found on all AVCN cell bodies. (C) Merged image of A and B. Filled arrows show M1-positive SBCs. Empty arrows show M1-positive cells which are not SBCs. (D) Digital magnification of the white square in C. Scale: 50 μm. (E) Calretinin staining in a parasagittal slice of gerbil cochlear nucleus in which endbulb of Held could be identified. Scale: 100 μm. (F) M2 muscarinic staining was mostly present in the anterior part of AVCN, around SBCs. Filled arrowheads indicate sparse but strong M2 staining close to cell bodies. (G) Merged image of E and F. (H) Digital magnification of the white square in G. Empty arrowheads point to M2-positive puncta on SBC cell bodies. Scale: 50 μm (magnification: 63x). D = dorsal; P = posterior; NR = nerve root.
