Robust concentration-dependent effect of desflurane on the sum of transfer entropies calculated between primary and secondary visual cortex (V1, V2), between cortical layers three and five (L3, L5), and between various subregions. Anesthetic states 1 to 9 correspond to consecutive desflurane concentrations of 0, 2, 4, 6, 8, 6, 4, 2, 0%, respectively. Transfer entropy sum is in relative units, plotted as mean and 95% CI. *Statistically significant quadratic trend with consecutive anesthetic states.
