Test Introduction
The Sucrose Preference Test, also known as the Two-Bottle Choice Test, is an established behavioral assay used to study drug addiction (including oral alcohol consumption) and depressive-like behaviors in animals. Rodents exhibit a natural preference for sweet tastes; however, the development of depressive-like behaviors leads to a measurable reduction in this sucrose preference. Anhedonia—the inability to experience pleasure—is a core feature of psychiatric and behavioral disorders. This aligns with the common human depressive symptom: “The world appears gray; I can no longer feel joy.” Based on this principle, the Sucrose Preference Test serves as a key tool for assessing depressive-like behavior in animals and evaluating the efficacy of antidepressant treatments.

The system indirectly measures fluid intake by recording the animal’s lick behavior. The software enables continuous 24/7 sampling and logging, allowing for time-phased analysis of drinking consumption.
