Figure 4.

Type II terminals are apposed to presynaptic ribbons in Prph−/− and Prph+/+ ears. A, B, Maximum projections of confocal z-stacks from the 11.3 kHz region of a knock-out and a wild-type ear, shown in the acquisition plane (x–y) and the orthogonal plane (z–y; Fig. 3C ). Green-filled, red-rimmed arrowheads point to appositions between (parvalbumin-positive) type II terminals and (CtBP2-positive) presynaptic ribbons. Red-filled, white-rimmed arrowheads in the z–y projections point to nonsynaptic ribbons. Scale bar and immunostaining keys apply to all panels. Dashed white boxes in the z–y projections show the z-cropping used to generate the x–y projections.
