“…More recently, MEG studies have expanded upon the extant Gf literature by illuminating the spatially and temporally specific oscillatory dynamics serving abstract reasoning (Arif et al, 2021;Taylor et al, 2020). Corroborating prior work, these studies found that spatiotemporal patterns of theta, combined alpha/beta, and gamma responses in occipital, parietal, and prefrontal regions uniquely served abstract reasoning in typically developing children and in healthy young adults (Arif et al, 2021;Taylor et al, 2020Taylor et al, , 2022. Unfortunately, despite the known impacts of aging on oscillatory dynamics (Arif et al, 2020;Proskovec et al, 2016;Rempe et al, 2022Rempe et al, , 2023Springer et al, 2023;, network communication, and Gf, no studies to date have examined the effects of aging on the oscillatory dynamics or dynamic functional connectivity underlying Gf.…”
