FIELD: medicine.

SUBSTANCE: group of inventions relates to a hardware-software complex for deciphering animal behavior patterns and a method of deciphering animal behavior using this complex. The complex contains a group of recording cameras (14) for placing laboratory animals (10), a subsystem for individual video surveillance (3) for animals, a subsystem for seismoacoustic recording of vibrations of the bottom and walls of each of the chambers and/or a subsystem for acoustic recording of sounds emitted by animals, a subsystem for synchronizing the video data stream and streams of acoustic and/or seismoacoustic data. The oscillations of the bottom and walls of the chambers caused by the motor activity of the animal are recorded by a seismoacoustic sensor as part of the subsystem of seismoacoustic registration (15). The analog signal from the seismoacoustic sensor passes through a cascade of filtering and preamplification before entering the analog-to-digital converter (7). The subsystem of acoustic recording of sounds (2) includes acoustic sensors of sound and/or ultrasonic frequencies, stages of amplification and filtering, and an analog-to-digital converter (6). The synchronization subsystem for the stream of video data and streams of acoustic and/or seismo-acoustic data includes a device-controller of a multimodal synchronization pulse (4), communication channels, and a monochromatic light source (1). The communication channels are configured to add a synchronization pulse (12) to the acoustic and/or seismic-acoustic data stream by connecting between the output of the filtering and preamplification stage and the input of the analog-to-digital converter. The light source generates a synchronization pulse in the optical range with the possibility of adding it to the video data stream. The wavelength of the light source is within the spectral sensitivity of video surveillance cameras, but outside the spectral sensitivity of the organs of vision of the studied laboratory animals. When performing the method, laboratory animals are placed in individual recording chambers. For each animal, video data, seismoacoustic and ultrasonic data are recorded. The data streams are synchronized with each other using a synchronization subsystem for the stream of video data and streams of acoustic and/or seismo-acoustic data with the possibility of automated formation of a collection of marked samples (22).

EFFECT: obtaining an automated method of deciphering patterns of animal behavior in long-term actographic experiments and a device for its implementation are provided, the said device and the said method are developed with the possibility of using already known and newly detected behavioral patterns for deciphering, increasing the speed and accuracy of deciphering animal behavior in the experiment.
