Nostril stitch does not affect accuracy. Gray shaded area represents the day of unilateral stitch. a, Percentage of correct Direct trials out of total number of Direct trials (no effect on accuracy, p > 0.05, Student’s t test). b, Percentage of correct serial trials out of total number of serial trials. c, Fraction direct trials. d, Averaged RMS deviation pooled for all rats for direct (blue) and serial (red) trials in forward (solid lines) and reverse (dashed lines) direction. No significant differences were observed for RMS values (data not shown). e, Total trial time for all rats for direct trials (blue) and serial (red) trials. f, Total time for direct trials pooled for all rats for three groups: pre-nostril stitch (pre-stitch, N = 425), nostril stitch (stitch, N=92), and post-nostril stitch (post-stitch, N = 243). Total trial time for stitch days are significantly higher than pre and post-stitch days (**p < 10⁻¹⁰, KW Tukey HSD test). g, Mean forward and return speeds for all rats. h, Mean speeds for direct trials in forward direction. Stitch day speeds were significantly lower than pre- and post-stitch days (**p < 10⁻⁷, KW Tukey HSD test). Error bars on all line plots are SEM.
