AIE also induced anxiety-like behaviors and enhanced ethanol intake in adulthood, which was attenuated by TSA treatment via normalization of deficits in histone H3 acetylation of BDNF and Arc genes. These novel results indicate that AIE induces long-lasting effects on histone modifications and deficits in synaptic events in the amygdala, which are associated with anxiety-like and alcohol drinking behaviors in adulthood.
