  1. The submental EMG was recorded during both MEG measurements. The number of swallows and the duration per swallow did not differ between the normal swallowing condition and swallowing with pharyngeal anesthesia (p > 0.05). The RMS of the amplitude over the time interval between M0 und M2 was significantly higher in the anesthesia condition compared to normal swallowing (p < 0.05).
