Table 1.

Integration times at 15 and 25° C determined (1) from the behavioral experiments, (2) from the shape of linear-range rod responses to brief flashes, and (3) from the light intensities needed at different stimulus pulse durations to produce a rod response of criterion peak amplitude in the linear range

Temperature (°C)	Behavior	Rods
		From model fits to responses to brief flashes	From threshold intensity versus stimulus duration
15	4.3 ± 0.9	4.2 ± 0.3	4.3 ± 0.4
25	≤0.9	1.3 ± 0.1	1.0 ± 0.1
