Regional electrode pooling for connectivity analysis.
Seven different regions were defined: three per hemisphere (frontal, parietal and occipital) and one central region [6].

Boxplots of the wPLI in the delta band.
(A) NR patients demonstrated a higher wPLI in wakefulness compared to sleep while (B) no difference is found between states in R patients. ⋆ Significant result at the level p<0.05 in post-hoc comparison”.
Fig 3.
Boxplots of the wPLI in the alpha band.
(A) In wakefulness, no difference was found between groups while (B) in sleep, a higher wPLI is found in NR group compared to R. ☆ Trend of significance in post-hoc comparison (p = 0.058).
Fig 4.
Linear regression between wPLI in the alpha band during sleep and the percentage of seizure reduction.
During sleep, a lower wPLI was observed in patients with a higher reduction in seizure frequency.
