Primary Assay — African Clawed Frog Tadpole
Optokinetic Response (OKR)
Xenopus laevis
Quantification of visually driven eye movements in response to moving gratings. OKR gain and contrast sensitivity provide non-invasive readouts of visual system function.
Quantitative Output
Measured Parameters
Every parameter is automatically tracked frame-by-frame in the ConductVision pipeline for Xenopus laevis.
| Parameter | Unit | Description |
|---|---|---|
| Slow-phase eye velocity | °/s | Tracking speed |
| OKR gain | ratio | Eye velocity / stimulus velocity |
| Contrast threshold | % | Minimum contrast for response |
