Supplementary Figure 5. The neocortical layers thickness was measured in the primary somatosensory cortex of the wild type (A) and homozygous Reeler mutant mouse (B), at the approximate level -2.1 mm from bregma (Hof et al., 2000), and found to be smaller in the mutant compared to the WT. In the CA1 region of the hippocampus  the pyramidal cell layers  occupied a larger area in the Reln^rl/rl mouse compared to the WT, while the stratum radiatum was thinner. In the dentate gyrus the upper blade of the molecular cell layer was thinner, while the upper blade of the granular cell layer was wider in the mutant. In the CA3 region of the mutant the pyramidal cell layer was thicker compared to the WT.
