Figure 2.

Interneuron dendritic arbors simplify with age. A, The number of primary dendrites of V1 interneurons does not change between 3 and 18 months (p = 0.23, unpaired two-tailed Student's t test, n = 51 for 3 months, 38 for ≥18 months). B, The distribution of total dendritic lengths in V1 does not change between 3 and 18 months (p = 0.059, Kolmogorov–Smirnov test, n = 51 for 3, 38 for ≥18 months). C, The distribution of the number of dendritic nodes shifts toward fewer nodes between 3 and 18 months (*p = 0.029, Kolmogorov–Smirnov test, n = 51 for 3, 38 for ≥18 months). Each n represents one cell for all panels in this figure. Error bars represent SEM.
