Sensor and source level functional connectivity differences during maintenance and emergence phases of sevoflurane general anesthesia in infants aged 0 to 3.9 months. (A) Statistically significant connections between different sensors during maintenance anesthesia compared with emergence (blue lines). (B) Sagittal, coronal, and axial views of connections between regions of interest for which connectivity was decreased during maintenance anesthesia compared with emergence. Data comes from n = 20 infants from 100-s epochs. Anesthetic depth range end-tidal sevoflurane was 1.8 to 2.5%, and emergence end-tidal sevoflurane was 0 to 0.3%.
