Embodiment 1

[0024] First make a Morris maze image automatic processing system according to Fig. 1, make a Morris maze bucket 1 by having determined four item limit orientations with iron sheet material, maze bucket 1 is diameter φ 100cm * height 78cm, is installed at the bottom of maze bucket 1 4 universal wheels 4 are used to manually adjust the position of the water storage root; a plexiglass is installed in the quadrant position of the maze barrel 1 to make a platform 5 for rats to find and land. Hole 3 is made at the bottom of the bucket, and a drainpipe 2 can be connected on the drain hole, so that water is discharged to a certain sewer. The experimental environment of the system: the background environment of the Morris water maze is milky white, and natural water diluted with milk powder at a temperature of 20-21 degrees is injected into the maze through the water supply system; the water surface exceeds a certain height of platform 5, ensuring that platform 5 is invisible in the ma...

Embodiment 2

[0027] The system in Embodiment 1 also includes an electric angle adjustment component installed on each wheel, and the angle adjustment component is driven by a motor to move the barrel, thereby obtaining an ideal tracking effect and collecting accurate data.

[0028] On the basis of the method of embodiment 1, according to the parameters of the search time required for the experiment, the search strategy, the orientation angle, the trajectory of motion, the speed of motion, and the position of entering the water, the above-mentioned parameters are analyzed with dBase and Spss methods, and then the data analysis chart is processed by the printer. That is, graphs, histograms, and trajectory graphs are printed out. The invention makes up for the defects of cumbersome work caused by manual recording and large errors in statistical analysis data.

Abstract

The present invention relates to experiment model for animal's learning memory and spatial cognitive action. The water maze image processing system includes one Morris maze barrel with definite four quadrant orientation and containing certain amount of water; one transparent stage for rat to search and land inside the barrel; and one down drainage hole in any point in the bottom of the barrel; aswell as characterized video camera, image monitor, image collecting card and computer connected together. The experiment method is that by means of the image monitor and the image collecting card, the video camera records automatically the tested animal's activity and relevant data, and the data are transmitted to the computer for real-time research and analysis.

Description

technical field [0001] The invention relates to an experimental model device for studying animal behavior, in particular to an automatic image processing system and processing method for an experimental model water maze (Morris maze) for studying animal learning and memory or spatial cognitive behavior. Background technique [0002] In the study of learning, memory or spatial cognition of experimental animals, it is usually necessary to place the animals in the experimental environment to complete certain pre-set behavioral tasks. One of the important experimental methods is to monitor the behavior of animals in behavioral devices. , especially real-time monitoring; the completion of this monitoring task has been completed by manual recording in the past, and even manual recording cannot be completed in complex detection tasks; this seriously affects the level of scientific research and makes the efficiency of animal behavior experiment research ver...
