What is the Forced Swim Test?
The Forced Swim Test (Porsolt test) is the most widely cited preclinical assay for antidepressant-like activity. Rodents are placed in an inescapable cylinder of water and alternate between active coping (swimming, climbing) and passive floating (immobility). Antidepressants selectively reduce immobility time, making this a primary pharmacological screen.
ConductVision uses water-surface tracking algorithms optimized for high-contrast aquatic environments. The software automatically classifies behavior into swimming, climbing, and immobility states using pose estimation, handles water reflections and splashing artifacts, and exports time-binned behavioral profiles for group comparisons.
