Recording from Type II terminal arbors. a. OHC cilia (white arrows). b.-c. Pipette attached to Type II fiber below OHCs. d. Confocal projection of dye-filled fiber (green). OHC nuclei (blue, DAPI) visible in rows (1-3), arrows (red) indicate fiber branches toward OHCs. Recording site (white arrowhead) near dye artifact ‘cloud’. e. Drawings of fill from (d) (P6, OHC row 2) and another fiber (P5, OHC row 1). f. Currents evoked by 10 mV steps from −80 mV. Inset: Selected inward currents, expanded. g. Current-clamp evoked action potentials (threshold: −32.1 ± 10.0 mV). Resting potential −56.9 ± 10.2 mV (n=10). Spontaneous action potential (inset) and small EPSPs (arrowhead). P5-9 rats.
