Newer studies using a multimodal approach, transcranial magnetic stimulation along with EEG, have shown a strong effect of ethanol on cortical connectivity especially over right frontal and also on left parietal areas (Kahkonen et al., 2001). In a recent interesting experiment that measured alcohol effects in real-world situations – a cocktail party and being in a driving simulator – an equation combining the beta and theta power was shown to be very successful in classifying alcohol and placebo, and the EEG score was significantly related to breath alcohol content (Gevins et al., 2012).
