Global perceptual behavior detecting device and animal cognitive behavior testing method

Abstract

The invention provides a global perceptual behavior detecting device. The global perceptual behavior detecting device comprises an open field, a display screen, a shading part and an image pick-up part, wherein the open field is of a box body structure with an open top and is composed of a bottom plate and a plurality of side plates which are connected end to end through enclosing; the display screen is arranged at the top of the open field, a display surface of the display screen faces to the surface of the bottom plate of the open field, and dynamic approach images are displayed on the display screen and comprise either images maintaining topological attributes or images transforming the topological attributes; the shading part is arranged on the surface of the bottom plate of the open field and is provided with a shading space; and the image pick-up part is arranged on the open field and is used for monitoring dynamic behaviors in the open field in real time. The behavior detectingdevice is a subconscious visual-stimulation detecting device, can be used for testing influence on animal behaviors caused by subconscious topological perceptions and can be used for reflecting relevance between the animal behaviors and global attribute perceptions to certain extent. The invention further provides an animal cognitive behavior testing method.

Description

Technical field [0001] The invention relates to the technical field of animal experiment equipment, and in particular to a whole-perceptual behavior detection device and an animal cognitive behavior test method. Background technique [0002] The visual and cognitive functions of the brain have always been the focus of neuroscience research. Among them, understanding the basic elements of visual perception is a basic problem in the study of vision. Studies have shown that there is a hierarchy of visual perception functions based on topology (overall attributes), and that the extraction of the topological attributes of objects is the starting point of visual perception. Topology here is a geometric definition, where the topological properties of a graph are the overall properties of the graph, which remain unchanged in various smooth shape changes and transformations of the image. For example, the number of holes is a topological property. A piece of plasticine, as long as it do...

Problems solved by technology

However, most of the above-mentioned devices need to train experimental animals for a long time, and need to consciously select experimental animals, eliminate the deficiencies such as unsuccessful training individuals, and the cost is high; and they cannot efficiently obtain the cognitive correlation of the overall attribute (topological attribute).
