Alcohol interferes with synaptic transmission throughout the cerebrum, especially in the prefrontal cortex (see figure 8–3), the region responsible for self-control. An inebriated brain is less inhibited sexually, verbally, and physically, giving us idioms like beer goggles, roaring drunk, and Dutch courage. Many studies have shown that people with a tendency toward violence are more likely to act on it when they are under the influence of alcohol.
