Fig. 2. Vomeronasal (VN) neurons are sexually dimorphic in soma size. (A,B) Histograms of the soma diameter of neurons harvested from male (A) and female (B) animals. Data were plotted in 1 µm bin widths and fitted with a normal distribution (solid line). The mean soma diameter of female VN neurons was significantly larger than that of males; Student’s t-test, 
=0.05. (C,D) As in A and B but for total neurite process length. Data were less well fitted by a normal distribution and not significantly different between female and male VN neurons (Student’s t-test, =0.05).
