Note: Top rows: quantification of balance between putative excitatory and inhibitory population activities (
(bs, ns) and 
). Middle row: quantification of dimensionality as measured by the PR. Bottom row: Spearman rank correlation between 
and PR; only 
values smaller than 0.05 are listed. All values were obtained from 3 s slices, for different behavioral states in REST (RSS, RS, M) and R2G (TM, PP), pooled across all recordings of the respective type.
