Primary Assay — Crayfish
Light/Dark Preference (Anxiety Analog)
Procambarus clarkii
Crayfish show robust scototaxis that is modulated by serotonin, directly paralleling mammalian anxiety paradigms. Time in dark zones, zone transitions, and latency to enter illuminated areas quantify anxiety-like states.
Quantitative Output
Measured Parameters
Every parameter is automatically tracked frame-by-frame in the ConductVision pipeline for Procambarus clarkii.
| Parameter | Unit | Description |
|---|---|---|
| Time in dark zone | % | Anxiety-like scototaxis |
| Zone transitions | count | Exploration balance |
| Latency to enter light | s | Risk-taking measure |
