Primary Assay — C. elegans
Touch Response (Mechanosensation)
Caenorhabditis elegans
Gentle touch to the anterior body triggers backward locomotion; posterior touch triggers forward movement. Response decrement with repeated stimulation measures habituation. Six identified touch receptor neurons.
Quantitative Output
Measured Parameters
Every parameter is automatically tracked frame-by-frame in the ConductVision pipeline for Caenorhabditis elegans.
| Parameter | Unit | Description |
|---|---|---|
| Response probability | % | Fraction of touches eliciting reversal |
| Response type | categorical | Full reversal, partial, or no response |
| Reversal distance | body lengths | Backward movement after touch |
| Habituation rate | slope | Response decrement across 10 touches |
| Habituation recovery | % | Response restoration after rest |
