Brief Exposure to Novel or Enriched Environments Reduces Sucrose Cue-Reactivity and Consumption in Rats after 1 or 30 Days of Forced Abstinence from Self-Administration (2012)

Abstract Environmental enrichment (EE) reduces drug and sucrose cue-reactivity in rats. In a previous study we reported that 1 month of EE (large cage, toys, and social cohorts) significantly reduced sucrose cue-reactivity. In the present study, we examined whether overnight (22 h) EE would be as effective. We also examined whether social enrichment (SE), enrichment […]
