HEADLINE

Alcohol Metabolites Directly Alter Brain Genetics with Impact Intensity Shifting Between Short and Long Term Exposure

SUMMARY

Researchers at Washington University in St. Louis have discovered that alcohol breakdown products directly regulate gene expression through epigenetic markers in the brain. The study, published in eNeuro, reveals that while lengthy exposure affects more brain regions, short-term alcohol use often produces more powerful molecular changes, particularly in areas governing emotion and motivation.
