Example of facilitation of the electrically-stimulated swallowing reflex by the cannabinoid agonist, WIN 55,212-2.

<p>The onset latency to the first swallow (A) and intervals between swallows (B) induced by different intensities of electrical stimulation of the SLN of naïve rats (n = 5). The ellipses indicate the characteristics of the swallowing reflex by the electrical stimulation at 4–5 µA. The typical example that the swallowing reflex by the SLN stimulation before (C), and two hours after (D), infusion of WIN 55,212-2. Note that WIN 55,212-2 decreases the onset latency to the first swallow and the intervals between swallows.
