Figure 3From: Type I vs type II spiral ganglion neurons exhibit differential survival and neuritogenesis during cochlear developmentQuantitative analysis of type I and type II spiral ganglion neuron (SGN) densities in P1, P7 and P21 mouse cochlea shows selective loss of type II SGNs in the first postnatal week in vivo. (A) Density of all SGNs, type I SGNs and type II SGNs calculated from cell counts taken from mid-modiolar cross-sections from P1 (black), P7 (grey) and P21 (white) mouse cochlea. Mean density ± standard error of the mean; ANOVA, post hoc Holm-Sidak test, **P < 0.01, ***P < 0.001. (B,C) The density of type I (B) and type II (C) SGNs within different regions of the spiral ganglion in mid-modiolar cross-sections are plotted against the distance of the ganglia from the apex of the cochlea.Back to article page
