The effect of 5-HT2 receptor antagonism on LTF in phasic glossopharyngeal nerve (IX) activity. (A) Average changes from baseline in peak amplitude of integrated IX activity, normalized as a percentage of the baseline (%baseline). (B) Changes from baseline in IX burst frequency (bursts/min). (C) Changes from baseline in minute IX activity, normalized as a %baseline. These values were obtained before and after 5 episodes of 3-min isocapnic hypoxia (12% O2) in vehicle (n=7) and ketanserin (n=6) rats. Data are expressed as means ± SE. * Significant difference from baseline. # Significant difference from ketanserin group (P< 0.05).
