EEG research is increasingly mapping oscillatory function to biological and neurological mechanisms, with complex interactions across space and frequency that subserve the integration of information in a hierarchically organized brain (Bonnefond et al., 2017; Canolty & Knight, 2010; Jensen & Colgin, 2007; Tingley et al., 2018). Oscillations at different frequencies are increasingly understood not to have a one‐to‐one mapping with function (Wolfgang Klimesch, 1999). Multiple functions may be present in oscillations, such as the multiple function linked to alpha oscillations: inhibition of sensory information during visual processing (Jensen et al., 2012; Jensen & Mazaheri, 2010; Klimesch et al., 2007; Yao et al., 2019), default mode function (Laufs et al., 2003; Mantini et al., 2007), and cortico‐subcortical communication (Horschig et al., 2015).
