What is the Marble Burying Test?
The Marble Burying Test places rodents in a cage with evenly spaced marbles on deep bedding. Animals spontaneously bury marbles through repetitive digging — a behavior sensitive to anxiolytics, SSRIs, and compounds targeting OCD-like repetitive behavior. The test dissociates compulsive-like digging from general anxiety and locomotor changes.
ConductVision uses overhead video tracking to monitor marble displacement in real time, automatically scoring burial depth and temporal patterns. The software counts buried marbles using contrast-based detection, tracks digging bout frequency, and separates burying behavior from incidental contact or exploration.
