Figure 4. Parameter Estimates under Isoflurane.

A Average dose responses at 1.4%, 1.8%, 2.4% and 2.8% for H_e (green) and H_i (grey) for region A1 from white noise condition (** p<0.005,* p<0.05; error bars denote s.e.m.). Overall trial effects are positive compared to zero baseline at 1.4% for the inhibitory parameters and negative for excitatory parameters. B Dose responses for H_e and H_i for region A1 from silence data. C Dose responses for H_e and H_i for region PAF from white noise data. D Dose responses for H_e and H_i for region PAF from silence data.
