Oscillations of electrical activity recorded by EEG reflect synchronized neuronal activity (Nuñez et al. 2000). Power within specified frequency bands indexes the average magnitude of oscillations over a specified time range, and coherence measures the extent of oscillatory coupling between two signals independent of their power. Both power and coherence of electrical activity during rest have been associated with fMRI measures of Default Mode Network (DMN) functioning (Britz et al. 2010; Laufs 2008). The DMN is a resting state network that includes the precuneus, posterior cingulate cortex, medial prefrontal cortex and temporoparietal junction (Gusnard and Raichle 2001; Hlinka et al. 2010), and is generally more active at rest than during task performance (Greicius et al. 2003; Li et al. 2002). DMN is thought to be involved in self-referential thought (Northoff et al. 2006; van der Meer et al. 2010; Fingelkurts and Fingelkurts 2011; Kim 2012) and autobiographical memory retrieval (Svoboda et al. 2006; Kim 2012), both of which are disturbed in psychotic disorders (Iqbal et al. 2004; Fisher et al. 2008; Holt et al. 2011). While fMRI studies have characterized
