FIG. 5.

Box plots of percentage change from effects of SCH23390 alone on the latency and amplitude of laryngeal conditioning R2 responses. The top traces show representative EMG recording of conditioning R2 responses changes induced by SCH23390 alone compared with the saline. Latency of conditioning R2 response decreased and amplitude increased after SCH23390 administration. Percentage changes of the response latency decreased at 5 min post SCH23390 administration and the latency maintained decreasing 1 h post SCH23390 compared with the saline control (*P ≤ 0.01, n = 10).
