Behavioral Tracking for Spiny Mouse
Acomys cahirinus
ConductVision delivers automated tracking of spiny mouse wound healing behavior, social interaction, and predator avoidance. Quantify behavioral recovery post-injury, social re-integration, and autotomy responses in Acomys cahirinus.
Why Spiny Mouse in Behavioral Research
The spiny mouse (Acomys cahirinus) is a remarkable mammalian regeneration model, capable of scar-free healing of skin, ear tissue, and potentially other organs. This makes them uniquely valuable for studying how behavioral recovery tracks with tissue regeneration — a question unanswerable in standard rodent models. Their social behavior, predator-avoidance autotomy response, and communal nesting provide additional quantifiable behavioral endpoints.

What We Measure in Spiny Mouse
Validated assays with quantitative parameter tracking for Acomys cahirinus.
Spiny mice regenerate skin without scarring, enabling unique studies of how behavioral function recovers alongside tissue regeneration. Locomotor activity, wound grooming, and social re-integration track functional recovery trajectories.
| Parameter | Unit | Description |
|---|---|---|
| Locomotor activity post-injury | % baseline | Motor function recovery |
| Wound licking/grooming | s/hour | Self-care behavior |
| Social re-integration latency | hours | Return to group after injury |
| Pain-related behavior reduction | days to baseline | Recovery trajectory |

Standard open field measures applied to spiny mice reveal locomotor activity, anxiety-like center avoidance, and vertical exploration. These measures serve as baselines for wound healing and regeneration studies.
| Parameter | Unit | Description |
|---|---|---|
| Distance | cm | Locomotor activity |
| Center time | % | Anxiety-like behavior |
| Rearing | count | Vertical exploration |

Spiny mice are communally nesting social animals. Investigation time, huddling behavior, and aggression frequency quantify social dynamics and provide endpoints for studying social recovery after injury.
| Parameter | Unit | Description |
|---|---|---|
| Investigation time | s | Sniffing conspecific |
| Huddling | s | Thermoregulatory social contact |
| Aggression frequency | events/10min | Agonistic encounters |

Spiny mice shed skin under predator grasp — a unique mammalian autotomy response. Escape latency, skin release threshold, and post-autotomy locomotion quantify this remarkable anti-predator adaptation.
| Parameter | Unit | Description |
|---|---|---|
| Escape latency | s | Time to flee from threat |
| Skin autotomy threshold | force (g) | Force required for skin release |
| Post-autotomy locomotion | % baseline | Movement ability after skin loss |
