Mean total number of errors	2.04 ± 0.29	4.50 ± 0.87	4.70 ± 0.64	6.10 ± 0.93	5.20 ± 0.77
Errors to first six phase 1 arms (during phase 2)	1.48 ± 0.22	3.70 ± 0.67	3.50 ± 0.50	4.35 ± 0.60	3.75 ± 0.53
Errors to remaining six baited phase 2 arms (during phase 2)	0.56 ± 0.14	0.80 ± 0.30	1.20 ± 0.27	1.75 ± 0.39	1.45 ± 0.29

Arm visits before an error, mean total number of errors, errors made to the first six arms (phase 1), and errors made to the remaining six baited arms (phase 2) ± SEM after no cannula– infusion-free (No cannula), PBS only (PBS), and three doses of scopolamine (Scop 6.31 μg, Scop 10.00 μg, and Scop 15.85 μg). Infusion volume was 0.15 μl/side.
