Quadruple FISH assay in a coronal section of adult mouse centered on A1 (from Fig. 7). a The image montages obtained at 40× in a show combined expression for VGAT, GAPDH, VGluT1, and VGluT2 mRNA, counterstained by DAPI. Subpanels 1–8 show 100× image stacks taken at sites in different layers of A1, as indicated in the composite image (left). b–g Higher-resolution examples of transcript labeling from subpanel 4 shown separately for each gene. Scale bars
a 250 μm, all other panels 20 μm
