Synaptic delays during systemic infusions. A: steady-state nitroprusside (NTE; n = 13). B: steady-state phenylephrine (PE; n = 9). C: modified Oxford (n = 9). Sample sizes for clusters in which not all subjects are included (clusters were not present) are indicated. Data are means ± SE. Data were analyzed with a 2-way repeated-measures ANOVA to determine the main effect of relative cluster size (10–100% of total clusters) and condition (baseline, drug) and the interaction of cluster and condition.
