Flash response parameters

Genotype Sensitivity i0, photons⋅μm−2 Dim-flash-response kinetics
Maximal response rmax, pA
tp, ms ti, ms
+/+ 69 ± 40 (10) 140 ± 20 (10) 270 ± 70 (10) 9 ± 3 (10)
+/− 118 ± 50 (16) 120 ± 10 (16) 190 ± 50 (16) 10 ± 2 (16)
Significance P < 0.02 P < 0.01 P < 0.006

Values are given as mean ± SD; number of measurements are given in parentheses. Significance was evaluated with Student’s t test. Abbreviations: i0, the flash strength at 500 nm producing a half-maximal response; tp, the time interval from the flash to the response peak; ti, the area of the response divided by its peak amplitude; rmax, the maximal saturating response amplitude.
