Abstract

The invention discloses an automatic training device of non-human primate touch sense research and a training method of the device. The automatic training device comprises a PC, a camera, a microcontroller, an animal seat and a multiple target selection grasping device, wherein the PC is provided with a display; the camera is connected with the PC; the microcontroller is connected with the PC by a serial port; the animal seat is used for fixing an experimental animal; the multiple target selection grasping device is located in front of the animal seat and divided into three layers, including a preparing button on the first layer, a grasping target object on the second layer and a judgement selection target object on the third layer; a prompt lamp is arranged on each layer, pressure sensors are fixed on the preparing button, the grasping target object and the judgement selection target object respectively, the grasping target object and the judgement selection target object are fixed on electric linear push rods which can move front and back, and the prompt lamps, the pressure sensors and the electric linear push rods are connected with the microcontroller respectively. According to the automatic training device, the training speed is greatly improved, and consumption of manpower resource can be saved.

Description

technical field [0001] The invention relates to the field of animal behavior training, in particular to an automatic training device for non-human primate tactile research and a training method thereof. Background technique [0002] In the field of brain-computer interface, especially in the field of implantable brain-computer interface, it is a very important step to use non-primate animals to replace and simulate humans for experiments. At present, great progress has been made in decoding the electrical signals generated by the cerebral cortex and applying them to the control of external devices, but there are few reports on decoding the formation mechanism of tactile sensation to form virtual tactile sensation through electrical stimulation. Prospects. [0003] In order to form different tactile sensations, it is necessary to adopt grasping training methods, using objects of different shapes, such as triangles, squares, spheres, etc., to grasp in a natural way. During t...

AI Technical Summary

Problems solved by technology

After the training is completed, it is necessary to collect synchronously the neural signals of macaques when they have tactile sensation. When simulating virtual tactile sensation, specific brain regions of macaques need to be electrically stimulated in time. It is necessary to record the electrical signals in the whole experimental process in detail and accurately. The above operations rely on manual work. are difficult to complete
