Automatic assessment system for visual cognition behavior function of rodent

Abstract

The invention discloses an automatic assessment system for a visual cognition behavior function of a rodent. The automatic assessment system comprises a shape sensory ability testing unit, a visual acuity testing unit and a photoreception ability testing unit, wherein the adjacent units are mutually engaged through a transition chamber respectively; the shape sensory ability testing unit is composed of at least three channels which are arranged side by side and are different in inlet shapes; the visual acuity testing unit is composed of a chamber body and a plurality of clapboards, the chamber body is provided with an inlet and an outlet, the plurality of clapboards are arranged in the chamber body at interval, the bottoms of the adjacent clapboards are staggered and provided with passageways, and each clapboard, side walls and floor are printed with texture patterns with different spatial resolutions respectively; and the photoreception ability testing unit is composed of at least three channels which are arranged side by side and are different in lumen illuminance. The automatic assessment system disclosed by the invention has the advantages that a set of complete test system which has no adverse influences on experimental animals is designed to realize the reliable assessment of the visual cognition behavior function of the rodent so as to establish complete and reliable assessment indexes.

Description

technical field [0001] The invention relates to an animal behavior evaluation system, in particular to an automatic evaluation system for visual cognitive behavioral functions of rodents. Background technique [0002] There are many strains or species of rodents, strong reproductive ability, easy feeding and management, strong experimental manipulation, and good visual function. They are considered to be ideal animal models for the experimental research of visual-related cognitive behavior. In the physiological, cognitive, and behavioral research experiments related to vision, it is usually necessary to first evaluate the visual perception ability and cognitive behavioral ability of the experimental animals, and screen out experimental animals with good visual function and appropriate cognitive behavior. In previous studies, the evaluation of visual perception and cognitive behavioral functions of experimental animals lacked systematic and objective, especially for rodents r...

Problems solved by technology

Some recent studies have used devices such as visual cliffs, water mazes, and rotating drum vision instruments to evaluate them in combination with animal behavior methods. The interaction of these factors is lack of system, usually accompanied by different degrees of damage to the animal's mental and physical health, so it is necessary to establish a test device with diverse evaluation capabilities, strong pertinence, and little impact on experimental animals

In addition, in more and more rodent visual cognitive behavior experiments, it is necessary to use implanted devices such as microelectrode arrays to collect neural signals at the same time. More comprehensive requirements require a systematic and comprehensive evaluation of photosensitivity, visual acuity, graphic recognition, and behavioral responsiveness. However, the current test method is single and lacks an analysis of the interaction between various indicators. At the same time, data records The degree of manual participation is relatively large, and there is no automated and reliable evaluation method

If there are more experimental animals that need functional testing, the manpower and material resources spent will be greatly increased
