The problem
Novel object scoring is subjective and labor-intensive
NOR requires timing how long an animal explores each object. "Exploration" is defined as nose within 2 cm and oriented toward the object — a judgment call that varies across scorers and fatigues over long sessions.
- Defining "exploration" (proximity + orientation) is subjective and inconsistent
- Dual-stopwatch scoring for two objects simultaneously introduces timing errors
- Four-object variants are nearly impossible to score manually in real time
The solution
Proximity-based interaction detection with orientation filtering
ConductVision defines configurable proximity zones around each object. Exploration is scored when the animal nose point enters the zone and head direction is oriented toward the object — matching the standard criterion, applied consistently.
- Configurable proximity zones (1-5 cm radius) around each object
- Head direction filtering ensures only oriented investigation counts as exploration
- Supports 2-object (standard NOR) and 4-object (spatial NOR) configurations

Applications
Recognition and memory paradigms
Standard novel object recognition
The classic NOR paradigm with familiarization and test phases. Automated discrimination index replaces manual scoring.
Measures
- Discrimination index (d2)
- Total exploration time
- Latency to first exploration
Object location memory
Object displacement variant where one familiar object is moved to a new location. Automated scoring detects spatial preference.
Measures
- Displaced object preference
- Location discrimination index
- Exploration per location
Recency discrimination
Which of two familiar objects was presented more recently? Automated scoring of recency preference across varying inter-trial intervals.
Measures
- Recency preference ratio
- Exploration time difference
- ITI effect on discrimination
Alzheimer model memory screening
NOR discrimination index declines with age in AD models. Automated scoring enables longitudinal tracking across large cohorts.
Measures
- Discrimination index by age
- Exploration motivation (total time)
- Age of discrimination failure
Compared to typical systems
How ConductVision differs
| Feature | ConductVision | Typical systems |
|---|---|---|
| Exploration criterion | Proximity + head direction | Proximity only or manual judgment |
| Multi-object support | 2-object and 4-object variants | 2-object only in most systems |
| Discrimination index calculation | d1, d2, d3 — all three standard | Usually one index, varies by system |
| Object zone configuration | Adjustable radius per object | Fixed zones |
| Bout-level data | Every interaction event logged | Cumulative totals only |
