Fig. 3. For incorrect trials, vibrissal removal causes rats localizing airflow to deviate more from the straight-line path to an airflow source but not a light source.
(A) Trajectories of all incorrect trials of five rats trained to localize airflow 10 days before vibrissal removal (top row) diverge less than after removal (bottom row). (B) For incorrect trials, deviation of each rat before vibrissal removal (blue) is smaller than after removal (red). Error bars show means ± SEM. ****P < 0.0001; **P < 0.01; *P < 0.05; n.s., P ≥ 0.05; Wilcoxon rank sum test; median values are reported in table S2. (C) The percentage of incorrect trials for which a nonneighboring fan was chosen before (blue) and after (red) vibrissal removal. ***P < 0.001; n.s., P ≥ 0.05; Yates’s corrected χ2 test.
