Emotional states are powerful modifiers of behavioral response and are becoming ever more ensconced in neuroscience research. The dysregulation of emotional states is a key facet of multiple psychopathologies, making measures of emotional state of interest in preclinical models of mood disorders, anxiety disorders, drug addiction, eating disorders, or even autism. The present chapter discusses the expression of emotional states in behavior, evaluates evidence that 50-kHz ultrasonic vocalizations in the rat are indicative of a positive emotional state, and discusses common neural substrates for the processing of rewards in rats and humans that may subserve the genesis of emotional behavior and its psychopathology.
