摘要: The esophagus plays a major role in the act of swallowing. aim present investigation was to apply whole-head magnetoencephalography order study cortical processing esophageal sensation healthy humans whom representation swallowing had been established previously. proximal stimulated nine participants by intermittent 5 ml water infusion. Submental EMG recording used identify trials, which were contaminated subsequent Esophageal stimulation led changes rhythmic activity brain that localized left lateral primary sensorimotor cortex. pattern activation showed same hemispheric lateralization as volitional swallowing, however, being more lateral. close anatomical vicinity these two functions points an important physiological link between and control
