Researchers have identified a genetic mechanism that regulates behavioral adaptations to emotional experiences by forming R-loops, unique RNA:DNA structures that activate target genes. The study focused on NPAS4, a gene implicated in stress and drug addiction, showing how blocking R-loops prevents maladaptive behaviors like cocaine seeking and stress-induced anhedonia in mice.
