Robean: A Standalone Freeware for Automated Rodent Neurobehavioural Analysis with Integrated Tracking, Visualization, and Reporting

Abstract

Quantitative analysis of rodent behaviour is fundamental to neuroscience, preclinical drug discovery and neurotoxicology research. Although several commercial and open-source software packages are available for behavioural assessment, some are expensive, some require programming expertise, and some provide limited flexibility for user-defined experimental configurations. To address these limitations, we developed Robean, a freely available standalone software platform for automated rodent neurobehavioural analysis from both live camera feeds and pre-recorded videos. Robean provides an intuitive graphical user interface that enables users to design experimental arenas, define custom analysis zones, perform spatial calibration, and automatically track rodent movement without requiring programming knowledge. The software currently supports automated analysis of three widely used behavioural paradigms: the Morris Water Maze, Elevated Plus Maze, and Open Field Test. Robean extracts behavioural metrics including escape latency, path efficiency, platform crossings, target quadrant preference, thigmotaxis, locomotor activity, zone occupancy, arm entries, and centre exploration specific to behavioural tests. In addition, the software generates trajectory maps, occupancy heatmaps, comma-separated value (CSV) datasets, comprehensive PDF reports, and batch study summaries for multiple experimental sessions. Developed using open-source software technologies and distributed as a standalone freeware application, Robean provides an accessible and reproducible solution for behavioural neuroscience laboratories. Its modular architecture facilitates future integration of additional behavioural paradigms and analytical modules, making it a flexible platform for automated rodent behavioural assessment.
