Effects of desflurane and visual flash stimulation on cortical neuronal interactions as measured by integration and complexity. Note that desflurane was administered from high to low concentrations. The steepest increase in integration occurs from 6 to 4% desflurane (shaded region), close to regaining consciousness. Poststimulus complexity plateaus at 4% desflurane. *Significant at alpha = 0.01 for 0 to 4% combined versus 6 to 8% combined. Post = poststimulus; Pre = prestimulus.
