Figure 2

Screenshot of continuous EEG, spectral EEG analysis, and SSEPs (somatosensory evoked potentials) at the end of the procedure. EEG monitoring under general anesthesia shows persistence of α-like activity (top) with a peak frequency around 9-10 Hz (left). Right corner of the image: SSEPs monitoring is shown. Physiological neuraxial propagation of peripheral stimuli (darker line) with no time delay is seen (from left to right: the first column is right upper limb channel, and then the right lower limb and the left lower limb channels are shown, second and third column, resp.).
