For each genotype, the top row indicates the number of GFP⁺ cells in each layer as a percentage of all SOM cells (GFP⁺ or tdTomato⁺) counted in each brain, averaged over all brains of that genotype. The SEM indicated in parenthesis. The bottom row expresses the same counts as a percentage of all SOM cells in each layer. These data are plotted in Figure 1B. The last row of the table quantifies the distribution of all SOM cells by layer, averaged over all 17 brains.
