Fig. 7. Auditory brainstem response thresholds (A) and distortion product otoacoustic emissions (B) in adult TrkB^shc/- mutant and TrkB^shc/+ control mice. ABR thresholds were elevated at all frequencies tested, and DPOAEs were absent in TrkB^shc/- mutants compared with controls. Amplitude of DPOAE determined at 2xf2-f1 (f1=8.86 kHz; f2=10.99 kHz; delta I1-I2=10 dB). DPOAE, distortion product otoacoustic emission; SPL, sound pressure level; ABR, auditory brainstem response.
