Extended Data Fig. 4: The laminar distribution of local axons and long-range axons for each dendrite subtype.

(a) Correlations of local axon lengths and long-range axon length for IT, PT, and CT neurons, respectively. Linear regression, P values and R2 are shown, the shaded areas around the regression line indicate 95% confidence intervals. P values were calculated via two-sided t-test. (b) Laminar distributions of local axons and long-range axons for each dendrite subtype. Red, local axons. Blue, long-range axons. The shade areas around the line indicate SEM. Bottom, laminar difference between local axons and long-range axons. Data are presented as mean ± SEM. Statistical analysis was performed by two-side Wilcoxon rank sum test, FDR correction for multiple comparisons. Exact number of neurons for each dendrite subtype can be found in Supplementary Table 4.
