Laboratory    Animal       Behavior          Observation             Registration and                Analysis                   System LABORAS is a high throughput system for automated recognition of a large number of rat and mouse behaviors. LABORAS is completey non-invasive, uses a home cage environment and automatically determines accurate and consistent behavioral data without the need of human observers. In addition LABORAS calculates precise position tracking parameters.    The innovative LABORAS technology is based on measuring the forces induced by the animal's movement and uses advanced pattern recognition technologies and Artificial Intelligence (AI) to convert these forces in behaviors and tracking information. The force measurement really measures the intensity and details of a movement and doesn't require light which is an important benefit with respect to the nocturnality of mice and rats. These system characteristics enable much more accurate recording and analysis of laboratory animal behavior than possible with video technology.   LABORAS determines the following validated behaviors and tracking information of mice and rats (please click on the movie icon behind the beaviors to see examples of the LABORAS functionality):   Normal behaviors Rats and Mice Group 1 (basic) Climbing (mice only) Locomotion  Immobility Rearing Group 2 (advanced) Grooming Drinking Eating Special Behaviors Rats Hindlimb licking (Formalin test)  Scratching Wet Dog Shakes (WDS) Head shakes / twitches   Purposeless chewing  Mice Scratching Seizures: Barrel rolls & Tonic Clonic Seizures: Racine scale P4 & P5 Freezing Startle response Tracking information Rats and Mice Position tracking info Position (X,Y) Speed Avg. speed Max. speed Time of max. speed  Traveled distance Position distribution Circling info    Nr. of circles (CW and CCW) Avg. time in circle Avg. speed in circle Avg. circle perimeter Special Cages Rats and Mice Light Dark Cage Nr. of entries in Dark part Nr. of entries in Light part Time spent in Dark part Time spent in Light part Legacy time (to Dark part) Mice Open Field (simulated) Special Cages Mice Sociability Cage (3-Chamber Cage) Nr. of entries in Left part Nr. of entries in Left Social Zone Nr. of entries in Right part Nr. of entries in Right Social Zone Nr. of entries in Center part Time spent in Left part Time spent in Left Social Zone Time spent in Rigt part Time spent in Right Social Zone Time spent in Center part Special parameters Rats and Mice Energy parameters  Estimated Energy  expenditure of animal (all movements)
