8 kHz synaptic cochleogram.

<p>Synaptic ribbon count measured at the 8 kHz tonotopic position within the cochlea. Despite the absence of a statistical difference in OHC counts, the wild-type mice demonstrated significantly greater post-noise exposure synaptic ribbon density per IHC (9A). Projections (60x, 3x zoom, oil immersed) of confocal stacks (9B) of immunostained pre and post-noise exposure mouse IHC synaptic ribbons (green, mouse anti-CtBP2).-/- = <i>Nox3</i>^<i>het</i>/<i>Nox3</i>^<i>het</i>:-/+ = <i>Nox3</i>^<i>het</i>/+: +/+ = wild-type.
