Figure 6

The relationship between outer hair cell loss and the density of NADPHd+ and PV+ neurons. Both panels show data from the AVCN (black) and DCN (gray) symbols. Data from the PVCN showed no statistically significant trends and is not shown. A: Density of PV+ neurons as a function of OHC loss did reveal a statistically significant relationship in both the AVCN and the DCN. B: Density of NADPHd+ neurons as a function of outer hair cell loss revealed no significant correlations, although there was a relatively high regression coefficient (r = 0.90; P = 0.19; 0.94, P = 0.15 for AVCN and DCN, respectively). No other cochlear histopathology correlated with either NADPHd or PV densities in any of the three CN subdivisions. All data were normalized to the greatest value from the dataset in each study.
