Automatic grabbing training and recording device for non-human primates

Abstract

The invention provides an automatic grabbing training and recording device for non-human primates for solving the technical problem how to enable trained primates to rapidly grasp various specified grabbing actions. The device comprises a rotating disc body, a microcontroller, a water feed control system, a brain electrical signal recorder and a PC. The device is easy to operate and high in training efficiency. The training mode is adjustable as needed, and the training paradigm of different grabbing masks can be achieved; the gestures are accurately detected, the specified experimental paradigm is conveniently designed, data precision of follow-up analysis is improved, and later analysis and arrangement are convenient. According to the automatic grabbing training and recording device, specified gesture grabbing training of non-human primates can be achieved, the grabbing training of the non-human primates can be rapidly and efficiently achieved through the painless automatic training process, manpower resource consumption can be greatly reduced, and the automatic grabbing training and recording device is applicable to research and development of rehabilitation therapy instruments in the field of brain-computer interfaces.

Description

technical field [0001] The invention relates to a recording device and method for non-human primate grasping behavior training, which is mainly applied to the research of brain-computer interface oriented to motor function. Background technique [0002] In the field of brain-computer interface research for motor functions, especially in the field of implantable brain-computer interfaces, it is a very important step to use non-human primates to replace and simulate humans for experiments. Among them, the research on the fine grasping movement of the hand is a frontier scientific issue in the field of brain-computer interface. It is of great significance to train animals to quickly master various prescribed grasping movements. At present, the common grasping training method is mainly to use objects with different shape characteristics, such as handles, flat plates, small rings, etc., to use natural grasping methods for grasping. Since multiple grasping modes often need to be ...

Problems solved by technology

In addition, judging whether the animal can grasp in the correct posture in an experiment, and how to give rewards in time when the experiment is successful, these problems often need to consume a lot of human resources for adjustment and observation, and are prone to misuse and cause animals to lose their grip. Training behavior is inefficient and ineffective

During the experiment, it is also necessary to collect the nerve signals of experimental animals synchronously. Due to the short time and high frequency of nerve electrophysiological signals, the synchronization requirements for motion data are also relatively high (less than 1ms), and it is necessary to record the entire data in detail and quickly. For each movement stage in the grasping process, the above experimental operations are difficult to complete manually
