Figure 4From: How does a surgeon’s brain buzz? An EEG coherence study on the interaction between humans and robotInter-hemispheric coherence changes between laparoscopic and robotic modality. Sample of inter-hemispheric coherence changes in the same surgeon operating with a laparoscopic (top raw) or a robotic (bottom raw) approach is shown in panel A. The bottom panel (B) shows the mean value of coherence function in the range of upper alpha and beta band; different from intra-hemispheric coherence, surgeons operating with the robotic device show significant higher values. Inset on the upper left side represents an exemplificative pattern of inter-hemispheric channel comparisons.Back to article page
