aFor each HC-NC electrode pair and sleep stage (N2 vs N3), the significance of the NC-GE occurrence times relative to the HC-SS onset was determined (see Fig. 3A; Materials and Methods). We then tallied the proportion of significant channel pairs according to their HC location (aHC, pHC), NC location (see Extended Data Table 4-1; Fig. 5A), and GE type (TB, DS, SS, US). These proportions were then entered into ANOVA. LO, Lateral occipital; LT, lateral temporal; CG, cingulate; OF, orbitofrontal; PF, prefrontal; PC, paracentral; MTO, medial temporo-occipital; MOP, medial occipito-parietal; IS, insula; LP, lateral parietal; NS, not significant (for post hoc Tukey's range tests, p > 0.1).
