Peak of the mean profile: wild-type 9.2 intersections at 60 um, knockout 8.7 at 70 um A. Welch t-test at each of 20 radii, neurons as n (48 vs 48): 0 with p < 0.05 (radii: none); smallest p = 0.07 B. Total intersections per neuron, neurons as n, Welch t-test: knockout 94.0, wild-type 92.8, p = 0.85 C. Total intersections per mouse (mean of its neurons), mice as n (6 vs 6), Welch t-test: difference 1.1 (95% CI -20.9 to 23.2), p = 0.91 D. Welch t-test at each radius on mouse means, Benjamini-Hochberg adjusted: 0 radii with q < 0.05; smallest q = 0.98
