FreezeFrame has become the standard in the field for automated fear conditioning. It combines the sensitivity of the human observer with the objectivity and high throughput of automation. While infrared beams can detect gross movements of an animal from one part of the cage to another, FreezeFrame can detect the minute movements of grooming, sniffing, turning and rearing. And FreezeFrame monitors the animal 2-4 times per second, not once every 5 seconds, for far more objective and reproducible results.
Not a tracking system. A proprietary motion detection algorithm filters out shadows, light flicker and camera noise, and detects movements as small as 1 mm.
Fully validated. Greater than 90% concordance between FreezeFrame and trained human observers.
Ordering FreezeFrame:
Number of channels:
The basic 4-channel system uses one computer to record from up to 4 animals at once. 4 cameras are provided, with each camera viewing one animal. For 8- and 12-channel operation, 2 or 3 computers can be connected together via ethernet or serial cables. The user then interacts with only one computer, which in turn controls the others.
Order WaterMaze, LimeLight and/or FreezeFrame together as a single, cost-effective system that will perform almost any behavioral task.
