Alternating self-administration sessions of cocaine and heroin impact drug-related motivation and vocalisations in rats

Distinct patterns emerged in motivation and USVs between cocaine and heroin self-administration. Notably, USV frequency did not consistently align with motivation, especially when drug dosage changed. Future research may clarify this divergence.
