This system is based on high definition USB video camera, laptop computer and modern video analysis software. You may determine unlimited number of zones in the “open field” area and the system will calculate number of boundaries crossed, time, speed and distance travelled in each zone. Time of small moving such as sniffing and grooming will be also calculated. The shape of the arena can be a classical square, shuttle-box, T- or plus-maze. Screenshots demonstrate features of Setting tab (calibration, selecting regions, time of experiment etc) and Select Region tab (5 regions were selected; note that the region “0” covers entire area and therefore provides average distance, time and speed information).
