What is the Sucrose Preference Test?
The Sucrose Preference Test is the gold-standard measure of anhedonia — reduced capacity to experience pleasure — a core symptom of major depressive disorder. Animals are given simultaneous access to a sucrose solution and plain water. Healthy rodents strongly prefer the sweet solution; a reduced preference ratio indicates an anhedonia-like state.
ConductVision integrates with lickometer-equipped cages or bottle-weight sensors to track consumption in real time. The software calculates preference ratios, corrects for side bias through bottle position counterbalancing, and generates circadian drinking profiles for chronic stress models.
