Data demonstrating the influence of sealing the mouth on pharyngeal flow mechanics during selective XIIth nerve stimulation in three animals

		Medial XIIth stimulation		Whole XIIth stimulation
		Mouth open	Mouth sealed	Mouth open	Mouth sealed
V̇I,max (ml s−1)	Control	28.0 ± 7.1	22.9 ± 4.9	27.6 ± 0.28	20.7 ± 3.7

	% change	+145*	+104	+74	+131
Pcrit (cmH2O)	Control	−22.0 ± 4.9	−23.1 ± 6.2	−21.4 ± 6.1	−22.4 ± 8.9
	XIIth stim.	−26.5 ± 6.9	−41.5 ± 17.7	−48.1 ± 24.4	−49.8 ± 30.2
	% change	−20	−80	−125	−122
Rn (cm2O/(ml s−1))	Control	0.81 ± 0.09	1.00 ± 0.13	0.78 ± 0.23	1.03 ± 0.24
	XIIth stim.	0.44 ± 0.19	0.86 ± 0.30	1.06 ± 0.61	1.02 ± 0.58

Each variable was assessed during control trials and at the XIIth nerve stimulation frequency that resulted in the peak V̇_I,max (see Methods, Results and legend to Table 1 for details).

^*Significantly different from control.
