Data are shown as mean ± SD with the number of cells analyzed in parentheses. Idark, Circulating dark current; SPR, single-photon response; τrec, dim flash time constant of recovery; Io, flash strength that elicited a half-maximal response; τD, the dominant constant of photoresponse recovery from saturating flashes. *p ≤ 0.05.
