Theta phase coupling between the hippocampus and the neocortical sensory regions during movie encoding. A, Visualization of the sources of interest located in the left auditory cortex (red dots), left visual cortex (green dots), left hippocampus (gray dots), and the null region (cerebellum, pink dot). Each dot corresponds to the preferred source of a single participant, but note that some preferred sources were shared across participants. B, Mean theta phase coupling between the hippocampus and the three regions, respectively, left auditory cortex [hippocampus–auditory cortex (Hpc–AC)], the left visual cortex [hippocampus–visual cortex (Hpc–VC)], and the left cerebellum [hippocampus–cerebellum (Hpc–Cbm)] during the synchronous and asynchronous movies. The boxplots represent the mean ± standard deviation, and the errors bars indicate 5th and 95th percentiles. The dots represent individual means.
