Fig. 4From: Cerebral autoregulation and neurovascular coupling are progressively impaired during septic shock: an experimental studyTemporal evolution of cortical activity during experimental sepsis. Alpha/delta ratio of the ECOG signal in sepsis vs. sham (a) and septic shock (b) group. No difference is observed in the sepsis and sham groups. There is a significant decrease in ADR in the septic shock group between T1SS and T4SS. Data are presented as median ± mean absolute deviation; *p < 0.05Back to article page
