Ouabain Does Not Induce Selective Spiral Ganglion Cell Degeneration in Guinea Pigs

Figure 1

Histology of the guinea pig cochlea. The midmodiolar section of a guinea pig cochlea shows 8 different locations (basal = B1, B2; middle = M1, M2; apical = A1, A2, A3, and A4) along the cochlear spiral at a half-turn spacing (not showing the helicotrema). The number of SGCs in the spiral ganglion (SG) were counted and the number of hair cells (IHCs and OHCs) in the organ of Corti (OC) was determined for each location, except A4.
