Figure 1

Examples of pharyngeal reflexive swallowing (PRS) and pharyngo-UES-contractile reflex (PUCR) evoked upon pharyngeal air (Figure 1A) and water (Figure 1B) infusions are shown in a representative neonate. PRS is characterized by the occurrence of pharyngeal waveform, submental EMG signal, and UES relaxation. PUCR is characterized by an increase in UES pressure after the infusion.
