  • The geometric mean of the ratio of linear fit parameters, intercept and slope, under each adaptation condition to the same parameter under stationary reference condition. The statistical significance of the difference from unity is calculated with a Wilcoxon signed rank test. Overall 89% of the cells was significantly changed by adaptation in the preferred direction and 49% by adaptation in the null direction (see methods).
