What is the standard negative geotaxis (climbing) protocol?

The standard RING assay protocol: gently tap flies to the bottom of a climbing vial and record for 10 seconds. Measure the height climbed. Perform 3–5 trials per group with 10–20 flies per vial. Allow at least 1 minute between trials. Pre-condition with 2–3 practice taps. Most labs use 3–5 day old adults.

How long should I wait after CO2 anesthesia?

Allow a minimum of 1 hour recovery from CO2 anesthesia before any locomotor testing. Some labs recommend 24 hours for sensitive assays. CO2 affects locomotor activity, startle response, and climbing performance. Transfer flies using aspiration (not CO2) on the test day when possible.

What frame rate do I need for Drosophila locomotion?

30 fps is sufficient for walking speed and basic path analysis. For leg coordination, wing kinematics, or detailed startle response, use 100+ fps. C-start equivalent responses in flight assays may benefit from 200+ fps. Most standard webcams are adequate for climbing and walking assays.

Can ConductVision analyze my Drosophila locomotion videos?

Yes. Upload standardized Drosophila locomotion videos to ConductVision (vision.conductscience.com) for AI-powered analysis including speed quantification, path tracing, climbing height measurement, and behavioral scoring.

Filming protocol follows established Drosophila locomotion methodologies (RING assay, DAM system, FlyTracker). Upload completed videos to ConductVision for AI locomotion analysis.

How It Works

Select the developmental stage (adult or larva), locomotion types (walking, climbing, flight, startle response, courtship walk, larval crawling), camera positions (dorsal, lateral, ventral, high-mag), and apparatus (climbing vial, open arena, Y-maze, DAM tube, flight column, agar plate). Optionally enable high-speed video notes, acclimation protocols, and group size recommendations. The tool generates a numbered shot list with Drosophila-specific instructions and duration for each clip. Incompatible combinations (e.g. larval crawling with climbing vial) are automatically filtered. Download the protocol as a printable PDF.

Filming Best Practices

CO2 anesthesia requires minimum 1 hour recovery before locomotor testing — this is the most common source of artifact. Age-standardize your flies (3–5 day old adults for most assays). Separate males and females as they have different locomotor profiles. Maintain 25°C ± 1°C during recording. Test at consistent time in the light cycle. For negative geotaxis, use 10-sec recording after gentle tap to bottom, with 2–3 practice trials. For larval crawling, use dark agar (2% agarose) for contrast. Frame rate: 30 fps for walking speed, 100+ fps for leg coordination. Drosophila are extremely vibration-sensitive — isolate the recording setup.

Method

Filming protocol follows established Drosophila locomotion methodologies including the RING assay (Rapid Iterative Negative Geotaxis), TriKinetics DAM system, FlyTracker, and DART (Drosophila Arousal Tracking). Camera positions and apparatus settings follow published best practices for each assay type. Acclimation protocols include CO2 recovery timing and temperature stabilization per standard Drosophila behavioral neuroscience conventions. All computation runs locally in your browser — no data is uploaded.
