Intravenously injected DON inhibited rhythmic swallowing triggered by SLN stimulation.

<p>A. Typical sublingual muscle electromyogram (note the rhythmic swallowing induced by SLN stimulation). DON (3mg/kg bw) injection induced a rapid and powerful inhibition of the number of swallows. 3 minutes after DON application, only three swallow were triggered by SLN stimulation. B. Electrocardiogram and respiratory activity recorded before, during and after SLN stimulation. Note the blockade of respiration induced by swallowing during SLN stimulation in control condition and at recovery 74 min after DON injection.
