Theta activity and cognitive functioning: Integrating evidence from resting-state and task-related developmental electroencephalography (EEG) research (2024, methodology): “Importantly, stronger theta-gamma coupling during the tasks predicted better memory performance (Friese et al., 2013; Fuentemilla et al., 2010; Heusser et al., 2016; K ¨ oster et al., 2014, 2018).”
Rhythms of human attention and memory: An embedded process perspective (2022, background): “By now, there is abundant evidence for a key role of the theta-gamma PAC in human memory formation (Friese et al., 2013; Heusser et al., 2016; Köster et al., 2018, 2019b; see Figure 3D ).”
The Functional Interactions between Cortical Regions through Theta-Gamma Coupling during Resting-State and a Visual Working Memory Task (2022, background): “PAC has been reported across multiple brain regions under a variety of conditions, reflecting interareal communication and interactions between cognitive functions [34,35].”
Targeting neural oscillations with transcranial alternating current stimulation (2021, background): “For example, the sequencing of perceptual information carried at the gamma frequency (30 – 80 Hz) is bound into a sequence of items that are encoded into memory at the theta frequency (4 – 8 Hz) (Lisman and Jensen, 2013; Heusser, 2016; Axmacher, 2010).”
Top-down selection of visual working memory contents is supported by alpha-band phase-synchronized oscillatory networks (2025, unknown): “In contrast to many previous studies which have found θ - band synchronization during VWM, particularly in the hippocampus ( Heusser et al., 2016), but also in cortex ( Bahramisharif et al., 2018; Berger et al., 2019; Sarnthein et al., 1998), we found θ - band desynchronization.”
Frontal midline theta and cross-frequency coupling during short term memory and resting state (2022, unknown): “…as well as peak frequency is modulated by cognitive load, but not the accuracy of the memory recall, while based on earlier studies (Friese et al., 2013; Park et al., 2013; Heusser et al., 2016), the expectation was that theta-gamma phase-amplitude coupling is correlated with recall accuracy.”
