The article presents scientific findings without apparent bias, focusing on research implications.

Understanding how the brain processes rewarding experiences could help researchers better understand behaviors such as overeating, as well as conditions such as anhedonia—the inability to experience pleasure, a common symptom of depression. One way researchers study reward-related processes is through animal models. In rats, ultrasonic vocalizations (USVs), sounds that are too high-pitched for humans to hear, are associated with various emotional and motivational states, including responses to rewarding stimuli.
