Effect of desflurane on mutual information between neurons recorded in primary and secondary visual cortex (V1, V2), cortical layers three and five (L3, L5), and their subregions. Anesthetic states 1 to 9 correspond to consecutive desflurane concentrations of 0, 2, 4, 6, 8, 6, 4, 2, 0%, respectively. Mutual information is in relative units, plotted as mean and 95% CI. *Statistically significant quadratic trend with consecutive anesthetic states.
