Figure 6.

Performance during personalized bisection tests at 6 months of age for the homozygous (+/+, black), heterozygous (+/−, gray), and wt (−/−, white) rats. A, Bisection curves depict mean proportion of long responses as a function of signal duration (1–7) averaged across the two sessions. Durations were chosen for each animal according to their performance during the staircase paradigm (see Materials and Methods). B, C, Mean ± SEM values for the extracted parameters of the fitted bisection function: gamma (B) and PSE (C).
