The membrane current response of naïve hWR in a low Na⁺/Cl^– milieu. (A) Each sample trace was the current response to the double light pulses at each V_m. The symbols indicate the I_peak/I_end of the first responses (blue filled/open diamonds) and the I_peak/I_end of the second responses (red filled/open diamonds), respectively. (B) I-V relations of the I_peak; the first responses (blue symbols) and the second responses (red symbols). (C) I-V relations of the I_end; the first responses (blue symbols) and the second responses (red symbols).
