Note: Forty‐four EEG observations from 11 patients were included in the correlation of EEG with fMRI connectivity measures. EEG observations were considered if they fell within 48 hr of MRI. Type proportion gives the proportion of EEG channels with a type progressed beyond the A‐type (B, C, or D). Peak proportion gives the proportion of EEG channels with a θα peak. EEG time post‐fMRI gives the number of hours before that the EEG observation took place after the patient's MRI scan (negative values indicate that the EEG observation preceded the MRI scan). Given the more favorable statistics of peak proportion (less skew and greater variance), this measure was correlated with fMRI connectivity (Figure 5) after averaging across all available observations.
