Alcohol may shift the brain from connected into a fragmented state

The analysis revealed distinct shifts in the brain’s topology following alcohol consumption. When participants drank alcohol, their brains moved toward a more “grid-like” state. The network became less random and more clustered.

This investigation provides a nuanced view of acute intoxication. It moves beyond the idea that alcohol simply “dampens” brain activity. Instead, it reveals that alcohol forces the brain into a segregated state. Information gets trapped in local cul-de-sacs rather than traveling the superhighways of the mind.
