Chicken short hair cell nAChR has lower relative calcium permeability. (A) Representative I-V curves obtained by voltage ramp protocols used to define the reversal potentials in external calcium concentrations of 0.1, 1, and 3 mM. (Inset) Magnification near the Erev. Each I-V curve represents a different hair cell, and thus absolute amplitudes cannot be compared. (B) Average (± SEM) Erev as a function of external calcium concentration in chicken short hair cells (gray squares, 5–8 cells per point) compared with previously published data for rat inner hair cells (black triangles). (From ref. 9.)
