In my laboratory we study neural mechanisms of cocaine and opiate addiction, binge eating, reward, and motor skill learning in the mesolimbic and nigrostriatal dopamine systems in rat models of behaviors involving dopamine transmission. We analyze behavioral measures and activity of single neurons in conjunction with the animal's affective state measured via ultrasonic vocalizations (USVs) that rats emit. One USV frequency range signals positive affect, whereas another signals negative affect. USVs provide new insights into what rats are experiencing, sometimes surprisingly at odds with what experimenters presume.
