Interplay between preclinical indices of obesity and neural signatures of fluid intelligence in youth (2024, unknown): “Further, theta activity has been shown to be crucial in coordinating a wide range of cognitive processes, including selective attention 65 , working memory 92,93 , and ﬂ uid intelligence.”
Distinct neural oscillations predict individual differences in feedback-guided cognitive flexibility (2026, unknown): “…of top-down and bottom-up functions such that neurons coding for item-related information preferentially fire during particular θ phases ( Ratcliffe et al. 2022) and that stimulus-related γ activity ( > 30 Hz) is locked to specific θ phases ( Bahramisharif et al. 2018; Siegel et al.…”
Top-down selection of visual working memory contents is supported by alpha-band phase-synchronized oscillatory networks (2025, unknown): “…are widely established to predict performance in VWM tasks in electroencephalography (EEG) ( D. Wang et al., 2018; Pavlov & Kotchoubey, 2022; Ratcliffe et al., 2022; Sauseng et al., 2009), magnetoencephalography Top-down selection of visual working memory contents is supported by alpha-band…”
The representation of abstract goals in working memory is supported by task-congruent neural geometry (2024, unknown): “…long-range communication between brain regions [21,23–25], we targeted frontomedial theta (FMT) to posterior coherence as a measure of time-resolved long-range connectivity [40] and examined whether FMT was associated with the strength of neural geometries for task goals, stimulus, and responses.”
No effects of the theta-frequency transcranial electrical stimulation for recall, attention control, and relation integration in working memory (2024, background): “Previous work suggested a key role of the theta rhythm for neural control and communication (Colgin, 2013), and several recent studies linked frontal midline theta to control within and over WM (e.g., Cavanagh and Frank, 2014; Berger et al., 2019; Ratcliﬀe et al., 2022).”
Would frontal midline theta indicate cognitive changes induced by non-invasive brain stimulation? A mini review (2023, background): “The other component is a set of “executive processes” associated with goal-directed behavior that operates on the content of the storage or representational system managed by the PFC and related networks (Smith and Jonides, 1999; Friedman and Robbins, 2022; Menon and D’Esposito, 2022; Ratcliffe et a”
Directional prefrontal-thalamic information flow is selectively required during spatial working memory retrieval (2022, background): “In human, theta activity can be engaged by the working memory task (Herweg et al., 2020; Riddle et al., 2020; Ratcliffe et al., 2022).”
