Fig. 5.

Vertical section of rat retina double-labeled for mGluR7 and ChAT. The two bands of cholinergic amacrine cell processes labeled with an antibody against ChAT (A) are not congruent with the mGluR7-immunoreactive bands in the IPL (B). The micrographs are printed as mirror images and are aligned along a common midline, as indicated by the arrows. Corresponding points therefore are found at equal distances from the midline. Unspecifically stained, larger blood vessels are marked by stars. Abbreviations as in Figure 1. Scale bar, 50 μm.
