LTF of phasic glossopharyngeal nerve (IX) activity (%maximum). Average changes from baseline in peak amplitude of integrated IX activity were normalized as a percentage of the hypercapnic response (%maximum). These data were obtained before and after acute intermittent hypoxia (AIH, 5 episodes of 3-min isocapnic 12% O2) in vehicle (n=7), ketanserin (n=6) and MK-801 (n=6) rats. There is a significant interaction (F8,56=5.04; P<0.001) between the group factor (3 groups) and time factor. Data are expressed as means ± SE. * Significant difference from baseline. # Significant difference from other two groups (P< 0.05).
