Embodiment 1

[0030] A training device for the interception of three-dimensional moving targets in primate motion, such as figure 1 As shown, it includes animal seat, water reward module, multi-modal physiological information collection module, moving target interception module and human-computer interaction control module.

[0031] The animal seat is composed of a main frame and an experimental frame for fixing experimental animals.

[0032] The water supply reward module includes a water nozzle, a conduit, a solenoid valve, and a water storage bottle; the conduit connects the water storage bottle, the electromagnetic valve, and the water nozzle in sequence.

[0033] The multimodal physiological information collection module includes:

[0034] Implantable myoelectric acquisition system: including myoelectric amplifier, 5V DC power supply, implantable myoelectric electrode and AI expansion version, myoelectric signal is collected by implanted myoelectric electrode, and myoelectric signal i...

Embodiment 2

[0041] A training method for intercepting three-dimensional moving targets in primates, such as Figure 4 As shown, follow the steps below:

[0042] (1) After the training paradigm is started, the macaque starts the experiment process and initializes the random variables;

[0043] (2) The LED-0 located on the base plate lights up, and the macaque touches the FSR-0 and keeps still;

[0044] (3) The macaque touches the FSR-0 to meet the time requirements, and one of the three LED light strips randomly starts to turn on and off from the beginning to the end;

[0045] (4) When the light beads in the LED strip move to the touchable area of ​​the macaque, LED-0 goes out, the macaque intercepts the moving light bead, and the macaque stops when it touches the target light bead. The macaque needs to hold the target and maintain it for a certain period of time ;

[0046] (5) If the macaque grasps the target object within the set time and maintains it for a sufficient time during the ...

Abstract

The invention discloses a training device and method for three-dimensional moving target interception by a primate. The training device comprises an animal seat, a water supply reward module, a multi-modal physiological information acquisition module, a moving target interception module and a human-machine interaction control module. The device can be used for grasping action training of animals in a self-defined three-dimensional target interception process, flexible and adjustable three-dimensional motion space can be provided, and natural and reproducible action interception behaviors are allowed; and the moments of the animals in motion planning or execution stages are precisely integrated and quantified, synchronous acquisition of multi-modal physiological information is achieved, and natural interaction with the external environment is achieved. The training device and method have the advantages of being reasonable in design, more natural in man-machine interaction, high in integration degree and automation degree, easy and reliable to operate, free of manual intervention and the like, and automatic training of three-dimensional moving target interception by animals can be achieved.

Description

technical field [0001] The invention belongs to the technical field of experimental zoology testing and animal experiment devices, and in particular relates to a training device and method for intercepting three-dimensional moving targets of primates. Background technique [0002] The analysis of motion-related brain nerve information based on invasive brain-computer interface technology is a research hotspot for scholars at home and abroad, especially the interception of three-dimensional movement of upper limbs is the focus of brain nerve information analysis. Motion interception is under the guidance of vision, the limbs are activated, tend to the target, and finally meet the intercepted target at the expected position. This process involves neurons in the visual cortex responding to visual cues, and neurons in the motor cortex regulate activity in pre-motor planning and during locomotion, and are thought to be involved in voluntary movements such as action planning, init...
