Figure 6. Hippocampal phase amplitude coupling predicts novelty detection and memory updating.

(a) Top, post-saccade changes in PAC following (−50 ms to 750 ms) fixations to updated and repeated object-locations are displayed for a range of gamma amplitudes. Below, significant (P_FWE < 0.05, nonparametric cluster corrected) increases in PAC related to novelty are indicated. (b) Theta to gamma PAC during (−50 ms to 750 ms) fixations to updated object-locations varies with memory outcome. A significant (P_FWE < 0.05, nonparametric cluster corrected), negative subsequent memory effects is depicted in the bottom panel. (c) PAC did not differ in the moments leading up to (−750 ms to 50 ms) fixations to updated and original object-locations during Mismatch trials. List of Tables.
