Hearing Profile (A) and middle ear bone dissections (B–C) of <i>eeyore</i> mice.

<p>ABR thresholds of hearing (grey bars) and deaf (black bars) <i>eeyore</i> littermates at 4 (*p = 4.8×10⁻¹⁰) and 24 (**p = 1.2×10⁻¹⁰) weeks of age. The ossicles appear largely normal in deaf mice (C), comparable to normal morphology of the malleus, incus and stapes in normal hearing mice (B). M; manubrium of malleus, A; articulation surfaces of malleus and incus joint, T; tubercle, G; gonial angle, LI; attachment points of suspensory ligaments of incus, LP; lenticular process, C; capitulum of stapes, V; arched ventral crus, F; footplate. Scale bar: 1 mm.
