Axonal branching patterns in superficial sublayers of L5 PRC-projecting and CTh cells. A, B, Axon reconstructions of a L5 PRC-projecting cell (A) and a CTh cell (B). Arrowhead, Soma location; x, cutting end of axon caused by slice preparation. Note that L5 PRC-projecting cells often had the axon that returned from L1 to L2/3 (colored branches), but that was rarely found in CTh cells. C, Axon length distribution of L5 PRC-projecting (red, n = 25) and CTh (blue, n = 18) cells within superficial sublayers. Cortical depth was normalized by L1 thickness in individual preparations. 0, Cortical surface; thin lines, individual axons; thick lines, mean ± SD for L5 PRC-projecting and CTh cells. The axonal length distributions were different between the two types (p < 0.01, Kolmogorov–Smirnov test). Asterisks indicate significant differences between L5 PRC-projecting and CTh cells in each bin (p < 0.05, Mann–Whitney U test).
