Ultrasonic vocalizations: evidence for an affective opponent process during cocaine self-administration
DJ Barker, SJ Simmons, LC Servilio, D Bercovicz… - …, 2014 - Springer
Rationale Preclinical models of cocaine addiction in the rodent have shown that cocaine
induces both positive and negative affective states. These observations have led to the …
