Comparison of the average number of axo-somatic Gly-IR puncta per 100 μm of cell perimeter in normal hearing and 14-day deaf animals in the different SOC nuclei. For each nucleus a comparable number of neurons was examined in the LSO (n = 223 low-frequency neurons in normal, 222 low-frequency neurons in deaf, 255 high-frequency neurons in normal, and 248 high-frequency neurons in deaf), SPoN (n = 93 low-frequency neurons in normal, 131 low-frequency neurons in deaf, 126 high-frequency neurons in normal, and 106 high-frequency neurons in deaf), LNTB (n = 198 neurons in normal and 127 neurons in deaf), MNTB (n = 315 neurons in normal and 282 neurons in deaf), and VNTB (n = 143 neurons in normal and 135 neurons in deaf). Error bars are SEM and asterisks denote significance of P ≤ 0.05.
