Relationship between stimulus sites and response magnitude (number of pharyngeal swallows activated) and time delay

	Location, cm from CP
	2	5	8	11	14	17
Delay, s	3.9 ± 2.9	4.2 ± 3.4	3.4 ± 2.5	4.9 ± 2.5	5.3 ± 3.3	7.9 ± 4.8
Number of swallows	1.0 ± 0.0	1.0 ± 0.0	1.0 ± 0.0	1.0 ± 0.0	1.0 ± 0.0	1.0 ± 0.0
N	13	12	14	10	8	3

Values of delay and number of swallows are means ± SD. There were no significant differences among delays to activation of the EPSR caused by esophageal distension in a square wave pattern (P > 0.05) using ANOVA.

CP, cricopharyngeus; n, number of animals.
