alcohol regulates theta oscillations

conflict-related theta power ... was blunted by alcohol

Alcohol attenuated event-related theta across successive processing stages

significant attenuation by alcohol in the right ACC (p<0.01) and right SFG (p<0.005)

event-related theta power is reduced by moderate alcohol intoxication in ACC and fronto-parietal regions during conflict processing

Alcohol reduced the response preparation theta power bilaterally in the ACC (left: F(1,19)=8.8, p<0.01; right: F(1,19)=4.4, p<0.05) and the motor cortex (left: F(1,19)=8.0, p<0.02; right: F(1,19)=7.0, p<0.02)
