Rats emit 50-kHz ultrasonic vocalizations (USVs), a widely used measure of drug-induced motivational and affective effects and dopaminergic activity. Although psychedelic drugs are promising for addiction treatment, the effects of ayahuasca (AYA) on 50-kHz ultrasonic vocalizations (USVs) remain unclear.
