Primary Assay — Hydra
Feeding Response (Glutathione)
Hydra vulgaris
Reduced glutathione released by prey triggers stereotyped tentacle contraction and mouth opening. Latency and duration of the feeding response measure chemosensation.
Quantitative Output
Measured Parameters
Every parameter is automatically tracked frame-by-frame in the ConductVision pipeline for Hydra vulgaris.
| Parameter | Unit | Description |
|---|---|---|
| Mouth-opening latency | s | Glutathione to mouth open |
| Tentacle contraction angle | deg | Tentacle bending |
| Feeding response duration | min | Prolonged response |
| Threshold concentration | µM | Sensitivity to glutathione |
