Abstract excerpt

Anhedonia is a core symptom of depression. As it cannot be directly assessed in rodents, anhedonia is usually inferred from a reduced consumption of, or preference for, a reinforcer. In the present study we tried to improve the measurement of anhedonia by performing a detailed preference analysis based on the generalized matching law and tested its sensitivity in rats congenitally prone (cLH) or resistant (cNLH)...
