Figure 7. Density of spiral ganglion cells in the apical and middle turns of the rat cochlea. No distinction was made between type I and II SGCs. The first series of data (black area) corresponds to controls, whereas the second series (gray area) corresponds to styrene - exposed animals. Data are presented as group means ( SD), n = 5/ group. ** corresponds to a statistical significant difference (Student's t-test p < 0.01).
