From: Widespread theta synchrony and high-frequency desynchronization underlies enhanced cognition
Generalization to memory retrieval processes. a Adjacency matrices, reflecting relative recall vs. baseline synchronization, organized as in Fig. 1d. b Summed positive and negative connection weights in each network, showing a strong desynchronization effect in gamma-band and a synchronization in theta (P < 0.01 for both). There was a significant frequency-synchrony interaction (P < 0.01, χ 2 test). c 3D representation of gamma (top) and theta (bottom) retrieval networks, organized as in Fig. 1e. d Correlation of spectral power and phase synchronization across all regions (74) and timepoints spanning a retrieval trial (2). HG power and synchrony were significantly inversely correlated (Pearson correlation, r = −0.698, P < 0.01 via permutation test), while an ROI’s theta synchrony was positively but not significantly predictive of HG power (r = 0.11, P = 0.36)
