BehaviorAtlas Optomotor · Software Suite
Mouse Optomotor Analysis System · Software Suite
Precise OMR head movement capture with flexible visual stimulation — quantifying spatial frequency and contrast sensitivity thresholds for vision and neuroscience research.
Software Functions
BehaviorAtlas Optomotor Capture Mouse — stimulus control, OMR/OKR behavior recording, and multimodal synchronization.
OMR Head Movement Capture
Top camera records head and body movement during optomotor stimulation — high-quality raw video for OMR analysis.
AI-powered OKR Eye Tracking
AI tracks pupil trajectories at millisecond resolution for optokinetic response (OKR) during grating motion — significantly improving detection precision.
Multimodal Synchronized Capture
Integrates with BA-EyeTracking for synchronized eye-tracking and head movement data — multi-dimensional support for visual function assessment.
TTL Event Synchronization
Event sync module records timestamps and sync I/O signals — aligning optomotor stimuli, video, and external peripherals.
Spatial Frequency Threshold Assays
Stepwise spatial frequency adjustment to quantify visual acuity (VA) threshold — measuring fine pattern resolution capacity.
Contrast Sensitivity Threshold Assays
Adjust contrast at fixed spatial frequency to measure contrast sensitivity (CS) threshold — resolution in low-contrast conditions.
Stimulus Preview
Preview grating motion after parameter setup — verify frequency, contrast, and texture before recording.
Non-invasive Natural-state Recording
Unrestrained mice on elevated platform — non-invasive recording that reflects natural visual function without surgery or fixation.
Broad Research Applications
For ophthalmic disease models, drug efficacy assessment, visual development mechanisms, and neurodegenerative vision research.

Workflow
Dark adaptation and placement, parameter config, acquisition and stimulation — AI tracks OMR head movement to output visual thresholds.
Experiment Preparation
After dark adaptation, place mouse on central platform in optomotor apparatus for free movement before experiment.
- Dark adaptation duration per experimental protocol
- Place animal after health check approval
- Head freely mobile, no fixation required
Create a grating stimulus event in capture software — configure spatial frequency, contrast, opacity, grating texture, direction, and moving speed, then lock the gradient protocol after preview.
- Adjustable spatial frequency (cpd), contrast (0–1), and grating texture
- Stimulus direction, moving speed, duration, and refresh interval
- Lock protocol after full-screen preview confirmation
Experiment Execution
Top behavior camera records head and body movement synchronized with grating stimulus timeline.
- Full-field coverage of experiment area
- Continuous head and body movement video recording
- Synchronized marking with stimulus parameters
Visual stimulation begins in preset sequence on six-sided surround displays — gratings presented in configured temporal order, direction, and duration.
- Six-sided immersive optomotor environment
- Alternating stimulus direction cycles
- TTL peripheral synchronized triggering
AI algorithms analyze head pose to determine whether head movement tracks the rotating grating.
- Head: tracking determined by ear-center and nose-tip keypoints
- Automatic distinction of non-specific head movement interference
- Head movement data aligned with stimulus timeline
Data Analysis
Aggregate head movement tracking trajectories — AI auto-determines tracking status, outputs spatial frequency and contrast sensitivity threshold reports.
- Synchronized head movement trajectory recording
- Automatic tracking/non-tracking state determination
- Export OMR results, body keypoint tracking data, and statistical charts
