TABLE 1.

Parameters of flash responses in PPEF-2^+/+ and PPEF-2^−/− rods^a

Rod type	n	t_p (ms)	t_i (ms)	a (pA)	i_o (photons/ μm²)	r_MAX
PPEF-2^+/+	20	124. ± 8.6	368.8 ± 44.7	0.36 ± 0.03
	21				47.1 ± 2.3
	22					11.1 ± 0.7
PPEF-2^−/−	22	135.2 ± 3.5	359.5 ± 28.0	0.43 ± 0.03
	21				41.5 ± 2.3
	23					9.7 ± 0.6

Values are means ± standard errors of the means; t_p is the time to peak of dim flash response; t_i is the integration time of the dim flash response; a is the estimated amplitude of the single photon response derived from the variance/mean rates in experiments with multiple dim flash trials; i_o is the flash strength at 500 nm that gave rise to a half-maximal response; and r_max is the saturating photoresponse amplitude.
