Cell-size distributions of NF-M positive (+) and negative (−) neurons. The graphs are relative frequency (%) histograms of NF-M+ (black columns) and NF-M− (white columns) neurons ranked according to soma size in HVC (A), RA (B), LMAN (C), area X (D), L2a (E), and Hp (F). Gray columns represent the areas of overlap in the two distributions. The average soma sizes measured were (expressed as means ± SEM): for HVC, NF-M+ = 175.3 ± 6.7 μm2 (n = 66), NF-M− = 69.15 ± 2.25 μm2 (n = 190); for LMAN, NF-M+ = 185.0 ± 5.5 μm2 (n = 92), NF-M− = 53.9 ± 2.7 μm2 (n = 71); for RA, NF-M+ = 161.9 ± 4.1 μm2 (n = 119), NF-M− = 60.0 ± 3.0 (n = 96); for area X, NF-M+ = 177.3 ± 5.7 μm2 (n = 68), NF-M− = 48.2 ± 2.2 (n = 103); for L2a, NF-M+ = 48.8 ± 0.9 μm2 (n = 180), NF-M− = 46.5 ± 1.0 μm2 (n = 184); and for Hp, NF-M+ = 84.2 ± 4.9 μm2 (n = 12), NF-M− = 85.0 ± 0.9 μm2 (n = 219).
