33862028-6	2021	We report that on a behavioral economics task, HR rats have higher preferred brain-cocaine levels compared to LR rats but do not differ with respect to their demand elasticity for cocaine.	Cocaine	83-90	HR, lysine demethylase and nuclear receptor corepressor	Rattus norvegicus	47-49	
33862028-7	2021	In contrast, when tested on an intermittent access schedule of cocaine self-administration, which has been shown to promote several addiction-related endophenotypes, HR rats exhibited greater escalation of intake and more drastic reductions in cocaine demand elasticity.	Cocaine	63-70	HR, lysine demethylase and nuclear receptor corepressor	Rattus norvegicus	166-168
