摘要

Info-optical system for the monitoring of the movement of laboratory rodents. The present invention consists of an info-optical system designed to monitor the movements of laboratory rodents in experiments carried out in labyrinths such as open-field, t-maze and morris water maze and in training wheels of the voluntary or motorized type. The system locates, tracks and records the trajectory described over time by one or several infrared light sources fixed to the skin of the laboratory animal; this allows the determination of a set of variables such as: movement time, inaction time, frequency in different areas of the enclosure, shape of the path, length of the traveled path, instantaneous speed, average speed, maximum speed, acceleration and other magnitudes physical derivatives of these. Therefore, it allows an automatic monitoring of the movements of laboratory rodents, replacing the human operator. This system can be applied simultaneously in up to 6 instruments of training or experimentation of as many laboratory rodents. (Machine-translation by Google Translate, not legally binding)
