State maps defined by ratios of multiple frequency bands. State maps were defined according to the power for two different ratios: Ratio 1 (0.5–20/0.4–45 Hz) and Ratio 2 (0.5–4–5/0.5–9.0 Hz). Using these two different ratios, state maps with four different quadrants were calculated (Q1: top left; Q2: top right; Q3: Bottom left; Q4: bottom right). Each sample is represented with a vector (arrow). The vector is composed by two points. The first corresponds to the baseline values of each ratio for each sample. The second point (i.e. the arrow head) corresponds to the test period values. (a–d) Control, pre-Cort/Cort, Cef and Cort + Cef groups are depicted. The majority of the vectors point towards the right and up (in the direction of Q3). Meanwhile, vectors from the Cef group (blue) show an overall trend towards the right and down (also see f). (e) Vectors from all groups are presented simultaneously. (f) An average vector for each group is presented. As suggested by panels a-d, all groups with the exception of Cef presented an orientation towards Q3, while Cef presented an orientation towards Q4. (g) Comparison of baseline and test values for Ratio 1. The Control and Cef + Cort groups differed both in the baseline and the test periods. (h) Comparison of baseline and test values for Ratio 2, no significant differences between groups were found. (i) Detailed statistics for Ratio 1 and Ratio2. The presence of a significant effect for “Group” with significant post hoc analysis for baseline and test periods indicates that the Cef + Cort group cannot be compared using state maps. Error bars indicate Mean ± SEM, n.s. indicates non-significant. * and ** indicate P < 0.05 and P < 0.01, respectively.
