Primary Assay — Mexican Cavefish
Sleep / Activity
Astyanax mexicanus
Cave morphs of Astyanax show dramatically reduced sleep relative to surface morphs. Total rest time, bout structure, and arousal threshold are core metrics.
Quantitative Output
Measured Parameters
Every parameter is automatically tracked frame-by-frame in the ConductVision pipeline for Astyanax mexicanus.
| Parameter | Unit | Description |
|---|---|---|
| Total rest | min/24h | Cumulative sleep |
| Number of rest bouts | count/24h | Sleep fragmentation |
| Mean rest-bout duration | s | Sleep consolidation |
| Arousal threshold | stim. intensity | Sleep depth |
