The article reports a study using graph theory and resting-state fMRI to examine how acute alcohol intake reshapes brain networks in healthy social drinkers. Findings show a shift from a globally integrated network to a more fragmented, locally clustered topology, with reduced global efficiency and increased local efficiency and clustering, especially in occipital regions.

This work is of interest to psychology because it links subjective intoxication to objective network changes, illustrating how alcohol can alter information processing and perception. It also helps explain individual differences in responses to alcohol, a key area in understanding human behavior and cognition.
