Oscillatory activity may be more directly linked to synaptic function than more indirect measures from imaging modalities based on energy expenditure, such as functional MRI or 18F‐fluorodeoxyglucose (FDG) PET. As indicated above, prior studies have linked beta oscillations to GABA alpha receptor subunit genes in alcohol use disorders (Edenberg et al., 2004; Porjesz et al., 2002). Other studies have highlighted the role of GABA interneurons for various EEG oscillations in schizophrenia (Edden et al., 2009; Rowland et al., 2013). Investigating the ties between oscillations and synaptic function may complete the circle, linking genetic variants to behavioral disorders to brain function.
