Habitest Modular System - FreezeFrame Fear Conditioning (Coulbourn)
The Habitest system combined with the FreezeFrame software provides all the options needed for running fear conditioning experiment in small laboratory animals (levers, nose-pokes, stimuli, drug pumps, shockers...)
- Habitest system with maximum modularity and flexibility
- Video-based freezing detection
- Proprietary motion detection algorithm to filter out shadows, light flicker and camera noise – detecting movements as small as 1 mm
- Greater than 90% concordance with trained human observers
- Video images can be stored for future review
FreezeFrame is at video-based software for fear conditioning and has become the standard in its field. Combining the sensitivity of the human observer with the objectivity and throughput of automation, FreezeFrame is able to measure minute movements of grooming, sniffing, turning and rearing. The animal is monitored 2-4 times per second for data that is far more objective and reproducible.
FreezeFrame is not a tracking system – featuring a proprietary motion detection algorithm, the system filters out shadows, light flicker and camera noise to detect movements as small as 1 mm. FreezeFrame offers superior performance in low-light and is fully validated, with greater than 90% concordance with trained human observers.
Easily store and recall multiple stimulus protocols for training and testing phases. Video images can be stored for future review and also exported as QuickTime and AVI movies for presentation. Batch export of data and analyses to Excel allows for easy analyzing of % freezing, number of bouts, bout duration and intervals for specified periods.
Either white noise or pure tone can be delivered through the computer’s sound card. The FreezeFrame system accommodates multiple sounds of different amplitude, frequency and quality throughout a single trial. Stimuli – including lights, external sound generators and/or shock generators are also controlled though the computer.
