Fig. 5. Pooled summary data for the postsynaptic receptor response to AMPA and NMDA at 0 and 1 MAC halothane. The graphs show the mean slopes, derived from the linear regression lines through the dose-response values and normalized to 0 MAC. The receptor response to AMPA and NMDA is significantly depressed by the anesthetic (*P < 0.05, **P < 0.01).
