Electroencephalography (EEG) studies during the resting state have recently been conducted to investigate the effects of alcohol on the brain (Coutin-Churchman et al., 2006; Herrera-Díaz et al., 2016; López-Caneda et al., 2017). Neural oscillations are an important mechanism of neural networks (Buzsáki and Draguhn, 2004), and changes in neural oscillations during the resting state are reportedly associated with consciousness, cognition, behavior, personality, psychopathologies, and neurological diseases (Davidson, 2003; Kumari et al., 2004; Thatcher et al., 2005). In particular, Kounios et al. (2008) found that resting-state brain activity was related to brain activity during cognitive tasks. They suggested that neural oscillations during the resting state are associated with cognitive functions such as attention, memory, and problem-solving.
