Representative recordings obtained from a man with a clear laryngeal prominence during swallowing. A, B The voltage signals obtained from sensors 1–5 simultaneously are listed from the upper to lower position. The sensor sheet, in which sensors 1–5 were embedded in the order of upper to lower, was placed at the surface of the neck. Thus, sensor 5 was positioned lowest and was placed a bit higher than the laryngeal prominence. The traces were recordings lasting 2 s from the instruction to swallow. A Arrows a–k indicate positive peaks. B Each arrow indicates a positive peak evoked during swallowing
