Primary Assay — African Clawed Frog Tadpole
Visual Avoidance (Looming Stimulus)
Xenopus laevis
Looming stimulus avoidance assay testing visual processing and collision avoidance circuitry. Tadpoles respond to expanding visual stimuli with characteristic escape behaviors.
Quantitative Output
Measured Parameters
Every parameter is automatically tracked frame-by-frame in the ConductVision pipeline for Xenopus laevis.
| Parameter | Unit | Description |
|---|---|---|
| Avoidance probability | % | Response rate to looming |
| Reaction latency | ms | Time to initiate escape |
| Angular threshold | degrees | Size at response |
