nervous system
N |
• mice exhibit no gross abnormalities in size or shape of all major nuclei of the superior olivary complex
|
• reduced volume of the medial nucleus of the trapezoid body (MNTB) at P25 due to reduced neuron numbers without a reduction in cross sectional area
• small reduction in the lateral superior olive
• however, MNTB volume is normal at P4
|
• in the medial nucleus of the trapezoid body
|
hearing/vestibular/ear
N |
• mice exhibit a non-significant improvement in ABR thresholds for click and noise burst stimuli and DPOAE growth functions, amplitudes and thresholds
|
• amplitudes of wave IV are increased above 50 dB compared with controls
• however, overall latencies of ABR peaks are normal
