Primary Assay — Sea Lamprey
Locomotor Swimming (Undulatory)
Petromyzon marinus
Lamprey swimming is generated by spinal central pattern generators producing alternating left-right muscle activation. Swimming frequency, speed, wave amplitude, and burst-coast dynamics characterize locomotor circuit output.
Quantitative Output
Measured Parameters
Every parameter is automatically tracked frame-by-frame in the ConductVision pipeline for Petromyzon marinus.
| Parameter | Unit | Description |
|---|---|---|
| Swimming frequency | Hz | Body wave cycle rate |
| Swimming speed | body lengths/s | Forward velocity |
| Wave amplitude | mm | Lateral displacement |
| Burst-and-coast ratio | % | Active vs glide phases |
