These findings suggest that oscillations are not just biomarkers of, but essential components in neural communication and computation. Arguably, aberrant brain oscillations will result in deviant behavior. Brain oscillations have therefore been widely investigated in the context of psychopathology—including neuropsychiatric disorders—and variation in normal human behavior (Başar & Güntekin, 2008; Skosnik, Cortes‐Briones, & Hajós, 2016). This includes alpha oscillations related to intelligence (Doppelmayr et al., 2002; Thatcher, North, & Biver, 2007), slow oscillations (4–8 Hz theta and 1–4 Hz delta oscillations) in schizophrenia (Boutros et al., 2008; Sponheim, Clementz, Iacono, & Beiser, 1994), theta and beta oscillations in attentional deficits (Clarke et al., 1998; Snyder & Hall, 2006), and beta oscillations in substance use (Rangaswamy et al., 2002; Struve, Straumanis, Patrick, & Price, 1989).
