+/+ | 69 ± 40 (10) | 140 ± 20 (10) | 270 ± 70 (10) | 9 ± 3 (10) |

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.
