Problems solved by technology

[0004] However, most animal movement and cognition research systems require specially matched monkey cages, or cannot limit the behavior of animals, which makes animals in a relatively uncontrolled state before and after the reaction, so they cannot be used to study limb movement, Eye movement or recording of brain nerve signals; some cannot meet the experimental requirements of multi-task, accurate and repeatable measurement

Embodiment 1

[0020] This example figure 1 Said includes animal fixed seat, touch screen interactive system, water supply system, eye tracker device, hand movement tracking and recording system, myoelectric recording system, signal acquisition system, lower computer and upper computer; animal fixed seat includes main frame and Experimental basket, the experimental basket is composed of neck plate, waist plate, support column, and bottom basket. The main frame is a steel structure and fixed on the floor. The torso and legs of the human primate are confined in the bottom basket, and the arms can move freely in the space between the neck plate and the waist plate. The neck plate of the experimental basket is at an angle of 20 degrees to the horizontal plane.

[0021] The touch screen interactive system includes a touch screen, a display screen, LED prompt lights, a ready button, a buzzer, a PC, and an experimental control program; the PC is connected to two monitors, and one monitor is located...

Embodiment 2

[0029] After recording the weight of the experimental animal, place it on a fixed seat, fix the neck by a neck ring, and adjust the position of the seat according to the size of the animal. Then fix the lumbar restriction board and the back board to limit its leg lifting and retreat.

[0030] like figure 2 Operate as described, turn on the system, and enter the program. The entry procedure includes opening the central control program, opening the eye tracker device, and the electromyography recording system. Open the communication serial port between the lower computer and the upper computer. According to the purpose and requirements of the experiment, different test modes are selected. In this example, the static mode of the target object in mode 2 is selected. Enter the parameter selection setting, press the preparation button for a long time, the radius and color of the target object, the brightness refresh frequency of the touch screen, the time to touch the target obj...

Abstract

The invention discloses a research system for motion and cognitive functions of non-human primates based on a touch screen, and belongs to the field of biology. The system comprises an animal fixing seat, a touch screen interaction system, a water supply system, an ophthalmoscope device, a hand motion tracking and recording system, an electromyographic recording system, a signal acquisition system, a lower computer and an upper computer. The system can be used for a plurality of training modes, can adjust various important parameters on line, can accurately record the time of each stage in themotion execution process, can synchronously extract the characteristic vector of the motion direction of a tested eyeball, the electromyographic signals of a plurality of muscles on the arm, the movement track of a hand and the electrical activity of a cerebral nerve, The system is reasonable in design, can be used for neural electrophysiological research related to functions of vision, hearing,motion and the like, a multifunctional automatic animal behavior training method greatly improves the training speed, and facilitates design of related experimental paradigm and later data acquisitionand processing.

Description

technical field [0001] The invention relates to the technical field of animal movement and cognitive functions, in particular to a touch screen-based non-human primate movement and cognitive research system. Background technique [0002] Brain movement and cognitive functions have received a high degree of attention and have become an international research hotspot, and relevant progress has been continuously reported by top academic journals such as Nature and Science. Non-human primates, such as macaques, as the closest experimental animals to humans, have advanced and complex nervous systems, and can complete a variety of complex behavioral tasks through training, and have been widely used to replace and simulate humans for sports and Cognitive function and other related research fields. [0003] Predecessors have developed a series of systems for studying motor function and cognitive function, and touch screens have long been used to study motor function and cognitive f...
