a, Escape targets vs. trial number in the chronic obstacle removal experiments (three and zero baseline escape trials combined, and now including the minority of mice that performed >3 trials). For this plot, only successful escape trials are counted toward the trial number. The correlation between escape target and the number of stimulus-evoked escapes following obstacle removal is not significant: correlation coefficient r = -0.07, P = 0.6. b, Escape targets vs. time. The correlation between escape target and amount of time since obstacle removal is not significant: correlation coefficient r = -0.12, P = 0.3. See Extended Data Fig. 6 for correlations between escape targets and the amount of post-removal exploration in various parts of the platform. Lines show the linear regression fit, and the shaded area shows the prediction interval within 1 standard deviation.
