Embodiment 1

[0037] see figure 1 , an experimental device for guiding multi-gesture stretching and grasping motions in three-dimensional space according to the present invention mainly includes a three-dimensional electric slide table 1, a grasping object assembly 2, a button switch 3, a data acquisition card 4, and an EEG signal recording system 5 , an optical motion capture system 6 and a PC 7. The three-dimensional electric slide table 1 is an XYZ three-axis slide rail 10 driven by a motor 14. The main structure of the three-dimensional electric slide table 1 is composed of five slide rails 10, and a slider 16 is arranged on the corresponding XYZ three-axis slide rail 10. The object component 2 includes LED lights 27, various grasping objects 18 and built-in spacer touch sensors 31, and the grasping object component 2 is fixed on the X-axis slider 16 of the X-axis slide rail 10-1 in the three-dimensional electric slide table 1 by bolts On -1, the button switch 3 is fixed on the support...

Embodiment 2

[0058] see Figure 10 , the operation and experimental process of the present invention, the specific steps are as follows: the subject sits at a position 20-30 cm in front of the exercise platform in a comfortable posture, and sticks reflective markers on the exercise arm. The experimenter sets the experimental parameters on the parameter setting unit of the PC 7, starts to record the EEG signals on the EEG signal recording system 5, and starts to record the motion signals on the motion recording unit of the PC 7. At this time, the data of the PC The writing unit sends the digital label corresponding to "start recording" to the EEG signal recording system 6, and records synchronously with the current EEG signal. During a complete experiment, the logic control unit of the PC 7 controls the three-dimensional electric slide table 1 to move the turntable 17 to a designated coordinate point, and controls the rotation of the motor 14 on the turntable 17, so that the designated gras...

Abstract

The invention provides an experimental training device for multi-gesture stretching and grasping in three-dimensional space, which mainly includes a three-dimensional electric slide table, a grasping object component, a button switch, a data acquisition card, an EEG signal recording system, an optical motion capture system and PC. The device of the present invention can realize the multi-gesture stretching and grasping action at any position in three-dimensional space; it can simultaneously record the EEG signal, the movement track of the arm and the experimental state of the subject in the process of performing the task, and provide a time-aligned three-dimensional In the training process, the training mode and training parameters can be adjusted in real time on the PC according to the learning progress of the subjects to improve the training efficiency; the entire experimental process is automatically controlled by the PC to reduce manual participation. The invention can realize arbitrary combination of various grasping gestures and arbitrary spatial positions, realize fully automatic control of experiments, and simultaneously record three kinds of data of electroencephalogram signal, arm movement trajectory and experimental state.

Description

technical field [0001] The invention belongs to the field of bioengineering, and relates to an experimental training device for multi-gesture stretching and grasping in three-dimensional space, which can be used to guide primates to perform and simultaneously record three types of animals' brain signals, arm movement tracks and experimental states. data. technical background [0002] The basic motor functions of the stretching and grasping movements of the upper limbs of humans and non-human primates are also one of the hot topics in the research of motor neuroscience. Scientists usually need to record the neural signals of the brain's motor cortex, the position of the grasp and the gesture information of the grasp when the subjects (primates) grasp objects in different positions with different gestures, and then analyze the relationship between the neural signals and the movement of the upper limbs. corresponding relationship. [0003] At present, the commonly used experi...
