Percentages of time that rats performed each of the different whisking patterns, as quantified for rostral-most, caudal-most, and mid-array whisker positions

	SYN	ASYN			Total OP
		Pure ASYN	DF	SS
Rostral	13.60	68.62	15.80	1.98	86.40
Caudal	12.37	74.52	10.41	2.70	87.63
Mid-array	16.14	67.68	12.44	3.74	83.86

Note that mid-array percentages are not the average of rostral and caudal values. This is because the mid-array trajectories were deliberately calculated by averaging rostral and caudal whisker angles in each video frame. This ′blurred′ the details of individual rostral and caudal trajectories and thus provided a conservative estimate of the amount of ASYN whisking. Accordingly, the fraction of SYN whisking appears higher for the mid-array trajectories. See Materials and Methods and Figure 1C for details.
