Fig. 3: Group average differences between low- and high-range spectral slopes in healthy control (upper row) and schizophrenia (lower row).
From: Reduced temporal variability of cortical excitation/inhibition ratio in schizophrenia
Lower \(\mu ({\beta }_{{lo}})\) values (left column) compared to \(\mu ({\beta }_{{hi}})\) (middle column) are apparent in both study groups. The right column shows the difference (\(\mu \left({\beta }_{{hi}}\right)-\mu ({\beta }_{{lo}})\), with asterisk symbols denoting statistically significant bimodality (p < 0.05, adjusted) over most of the cortex with a parieto-occipital dominance.
