Changes in dendritic complexity come from changes in basal dendrite number (but not length) at multiple branch orders. a The number of primary basal dendrites is correlated to cortical position along a tangential gradient among C57;GFP/Cre⁺ neurons but not Itgb3^fl/fl;GFP/Cre⁺ neurons. b No correlation between average length of primary basal dendrites and cortical position along a tangential gradient among either C57;GFP/Cre⁺ or Itgb3^fl/fl;GFP/Cre⁺ neurons. c, d As in (a, b), in secondary basal dendrites. e, f As in (a, b), in tertiary basal dendrites. g, h As in (a, b), in quaternary basal dendrites. R² and p-values for (a–h) are summarized in Table 1. C57;GFP/Cre⁺ neurons were previously reported in Holley et al. [31] and re-analyzed for this study. C57;GFP/Cre⁺ N = 116 neurons; Itgb3^fl/fl;GFP/Cre⁺ N = 86 neurons, unless otherwise noted in Table 1
