oscillatory activity with high temporal resolution. Waking EEG and MEG activity has received intermittent attention as a potential indicator of altered neurotransmission in BD. A recent review of the BD literature suggests that increased theta and delta and decreased alpha band power are the most robust findings for resting EEG (Degabriele and Lagopoulos, 2009). However, not all studies of EEG power have yielded this pattern of results. For example, greater power in all frequency bands (El-Badri et al., 2001), and increased beta but decreased theta power (Howells et al., 2012) have also been reported.
