[0002] Microwaves refer to electromagnetic waves with a frequency of 300MHz-300GHz and a wavelength of 1mm-1m, which are widely used in industry, communications, medicine, military and other fields. With the widespread application of microwave technology, people have begun to pay attention to and worry about the impact of microwave radiation on health.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] The following describes a primate behavior testing device 1 suitable for a microwave exposure environment according to an embodiment of the present invention with reference to the accompanying drawings.

[0031] like Figure 1-Figure 5 As shown, the primate behavior testing device 1 suitable for a microwave exposure environment according to an embodiment of the present invention includes a control terminal 10, an operation terminal 20, a plurality of light-transmitting buttons 30, a plurality of color light sources 40, a plurality of press detection devices 50, a feeding trough 60, a pneumatic food delivery device 70 and a fixed chair 80.

[0032] A plurality of light-transmitting buttons 30 are installed on the operation terminal 20. A plurality of color light sources 40 are installed in the control terminal 10 and are respectively connected to the plurality of light-transmitting buttons 30 through a plurality of transmission optical fibers 41. A press detection device 50 is used to detect whether the light-transmitting button 30 is pressed. The plurality of press detection devices 50 are arranged in the control terminal 10 and are respectively connected to the plurality of light-transmitting buttons 30 through a plurality of detection optical fibers. A food trough 60 is arranged on the operation terminal 20. A pneumatic food delivery device 70 is arranged in the operation terminal 20 and is suitable for delivering food pellets 4 into the food trough 60. A fixed chair 80 is used to fix a primate 3. Among them, the operation terminal 20, the food trough 60, the pneumatic food delivery device 70 and the fixed chair 80 are all non-metallic material parts.

[0033] Specifically, the colored light source 40 transmits light of different colors to the light-transmitting button 30 via the transmission optical fiber 41 , so that the light-transmitting button 30 emits light of different colors, which is convenient for the primate 3 to observe.

[0034] The pressing state of the light-transmitting button 30 is transmitted to the pressing detection device 50 through the detection optical fiber, so that the pressing state of each light-transmitting button 30 is determined by the pressing detection device 50 .

[0035] The pneumatic food delivery device 70 delivers food pellets 4 into the food trough 60 through gas drive. The pneumatic food delivery device 70 is connected to a pneumatic pipeline for controlling the delivery timing to reward the specific behavior of the primate 3.

[0036] The operation terminal 20 and the light-transmitting button 30, the food trough 60, the pneumatic food delivery device 70 and the fixed chair 80 for fixing the primate 3 installed thereon constitute the operation terminal device, and the control terminal 10 and the color light source 40 and the press detection device 50 installed therein constitute the control terminal device. Since the operation terminal 20, the food trough 60, the pneumatic food delivery device 70 and the fixed chair 80 are all non-metallic materials, they will not affect the electromagnetic environment. The operation terminal device can be set in the electromagnetic exposure environment 2, while the control terminal device can be set outside the electromagnetic exposure environment 2. The operation terminal device and the control terminal device are only connected by optical fiber and pneumatic pipeline, avoiding the influence of circuit connection on the electromagnetic exposure environment, so that the primate behavior test device 1 suitable for microwave exposure environment can be used for primate behavior test in electromagnetic exposure environment.

[0037] Furthermore, the primate behavior testing device 1 suitable for microwave exposure environment can be used to evaluate the working memory of primates 3, and is designed based on the principle of the working memory paradigm - delayed matching task (DMTS). The basic logic of the DMTS task process is to keep the memory of the previously presented sample stimulus during the delay period, and then make correct matching choices for different detection stimuli, and measure the working memory performance with accuracy and reaction time as indicators.

[0038] Before the formal behavior test, the primate 3 needs to be trained in behavior. First, the primate 3 needs to be adapted to the primate behavior test device 1 and learn that it can obtain food rewards from the primate behavior test device 1. Then, it needs to learn to respond to light stimulation before it can obtain food. Finally, it needs to learn the rules of the DMTS task.

[0039] During the formal behavior test, after the control end device sets the task program, the primate 3 is fixed in front of the operation terminal 20 through the fixed chair 80, so that the primate 3 faces the light-transmitting button 30. The color light source 40 of the control end device presents visual stimulation to the primate 3 through the transmission optical fiber 41 and the light-transmitting button 30. The primate 3 performs a pressing operation under the visual stimulation, and the pressing detection device 50 determines whether the primate 3 performs a correct pressing operation by judging the pressing condition of the light-transmitting button 30 transmitted by the detection optical fiber. After receiving the signal, the control end device controls the pneumatic food delivery device 70 to deliver the corresponding food reward according to the performance of the primate 3 in the behavior task.

[0040] According to the primate behavior testing device 1 suitable for microwave exposure environment according to the embodiment of the present invention, by making the operation terminal 20, the feeding trough 60, the pneumatic food delivery device 70 and the fixed chair 80 all non-metallic materials, there will be no impact on the electromagnetic environment. The operation end device can be set in the electromagnetic exposure environment 2, and the control end device can be set outside the electromagnetic exposure environment 2. Moreover, the operation end device and the control end device are only connected by optical fiber and pneumatic pipeline, thereby avoiding the impact of circuit connection on the electromagnetic exposure environment and avoiding electromagnetic interference caused by the circuit connection. The primate behavior testing device 1 suitable for microwave exposure environment can be used for primate behavior testing in electromagnetic exposure environment, and the primate behavior testing device 1 suitable for microwave exposure environment has good electromagnetic compatibility, can be used not only in real-time microwave environment, but also suitable for electromagnetic radiation in various frequency bands, thereby improving the applicability of the primate behavior testing device 1 suitable for microwave exposure environment.

[0041] Therefore, the primate behavior testing device 1 suitable for a microwave exposure environment according to an embodiment of the present invention has the advantages of strong applicability and the like.

[0042] The following describes a primate behavior testing device 1 suitable for a microwave exposure environment according to a specific embodiment of the present invention with reference to the accompanying drawings.

[0043] In some specific embodiments of the present invention, Figure 1-Figure 5 As shown, the primate behavior testing device 1 suitable for a microwave exposure environment according to an embodiment of the present invention includes a control terminal 10, an operation terminal 20, a plurality of light-transmitting buttons 30, a plurality of color light sources 40, a plurality of press detection devices 50, a feeding trough 60, a pneumatic food delivery device 70 and a fixed chair 80.

[0044] Specifically, Figure 4 As shown, the light-transmitting button 30 includes a button box 31, a button body 32 and an elastic member 33. The button box 31 is disposed in the operation terminal 20. The button body 32 is movably disposed on the button box 31 between a pressed position and a lifted position and is exposed from the operation terminal 20. The elastic member 33 is disposed in the button box 31 and normally drives the button body 32 to move toward the lifted position, wherein the button box 31 and the button body 32 are non-metallic material parts. In this way, the light-transmitting button 30 can be pressed normally and reset by the elastic member 33, and the light-transmitting button 30 can have good electromagnetic compatibility.

[0045] It will be understood by those skilled in the art that since the elastic member 33 is far away from the head and body of the primate 3 , it has little effect on the microwave exposure of the primate 3 , and therefore can be made of metal material or partially of metal material.

[0046] Furthermore, the elastic member 33 includes a spring and a wave absorbing material layer wrapped outside the spring. Here, it is preferred that the thickness of the wave absorbing material layer is greater than or equal to 5 mm. This can further reduce the impact of the elastic member 33 on the microwave exposure environment.

[0047] Advantageously, the button body 32 is a nylon part. This can make the button body 32 have good self-lubricating properties, so that the button body 32 can slide smoothly, avoid the button body 32 from getting stuck, and ensure that the button body 32 can be pressed and reset smoothly.

[0048] Specifically, the operation terminal 20 is made of PVC (polyvinyl chloride) material.

[0049] There may be five light-transmitting buttons 30 .

[0050] More specifically, Figure 4As shown, the detection optical fiber includes a transmitting optical fiber 51 and a receiving optical fiber 52. Each pressing detection device 50 is connected to a light-transmitting button 30 through the transmitting optical fiber 51 and the receiving optical fiber 52. One end of the transmitting optical fiber 51 is connected to the pressing detection device 50 and has a transmitting end 511 away from the pressing detection device 50. One end of the receiving optical fiber 52 is connected to the pressing detection device 50 and has a receiving end 521 away from the pressing detection device 50. The transmitting end 511 and the receiving end 521 extend into the button box 31 and are arranged opposite to each other in the button box 31. A light shielding sheet 321 is provided on the button body 32. When the button body 32 is in the pressing position, the light shielding sheet 321 blocks between the transmitting end 511 and the receiving end 521. When the button body 32 is in the lifted position, the light shielding sheet 321 avoids the imaginary connecting line between the transmitting end 511 and the receiving end 521. In this way, when the light-transmitting button 30 is pressed, the button body 32 is located at the pressing position, and the shading sheet 321 is blocked between the transmitting end 511 and the receiving end 521, so that the light emitted by the transmitting end 511 is blocked by the shading sheet 321 and cannot be received by the receiving end 521. When the light-transmitting button 30 is lifted, the button body 32 is located at the lifted position, and the shading sheet 321 avoids the imaginary line between the transmitting end 511 and the receiving end 521, so that the light emitted by the transmitting end 511 can be received by the receiving end 521, so that the pressing detection device 50 can judge the pressing state of the corresponding light-transmitting button 30 through the receiving state of the light at the receiving end 521, and avoids setting an electric control structure at the operating end device, further ensuring the electromagnetic compatibility of the primate behavior testing device 1 suitable for microwave exposure environment.

[0051] Specifically, the pressing detection device 50 can be a light sensor. The transmission optical fiber 41 can be thicker than the detection optical fiber, so that the light-transmitting button 30 can emit light reliably and the brightness adjustment range of the light-transmitting button 30 can be increased. The color light source 40 can emit at least 7 different colors of light, namely red, yellow, blue, green, cyan, white and purple.

[0052] Figure 3 and Figure 5 FIG. 1 shows a primate behavior testing device 1 suitable for a microwave exposure environment according to some examples of the present invention. Figure 3 and Figure 5As shown, the pneumatic food delivery device 70 includes a delivery box 71, an upper delivery pipe 72, a lower delivery pipe 73, a slider 74, a first pneumatic pipeline 75 and a second pneumatic pipeline 76 (the up and down directions are shown by arrows in the figure and are only for the convenience of description, not for the limitation of the actual setting direction). The upper surface of the delivery box 71 is provided with an upper opening and the lower surface is provided with a lower opening, and the upper opening and the lower opening are staggered in the up and down direction. One end of the upper delivery pipe 72 is connected to the upper opening and the other end is connected to the air source 77. A food pill delivery port 721 is provided between the two ends of the upper delivery pipe 72, and the upper delivery pipe 72 has a spiral coil section 722 for storing food pills 4. One end of the lower delivery pipe 73 is connected to the lower opening and the other end is connected to the food trough 60. The slider 74 is provided with a pill opening 741. The slider 74 is slidably arranged in the delivery box 71 between a first position and a second position. When the slider 74 is in the first position, the pill opening 741 is opposite to the upper opening in the vertical direction. When the slider 74 is in the second position, the pill opening 741 is opposite to the lower opening in the vertical direction. The delivery box 71 is also provided with a first pneumatic opening and a second pneumatic opening. The first pneumatic opening and the second pneumatic opening are respectively located on opposite side walls of the delivery box 71. One end of the first pneumatic pipeline 75 is connected to the first pneumatic opening and the other end is connected to the air source. One end of the second pneumatic pipeline 76 is connected to the second pneumatic opening and the other end is connected to the air source. The first pneumatic pipeline 75 and the second pneumatic pipeline 76 are configured to be suitable for blowing the slider 74 to the first position through the first pneumatic pipeline 75 and suitable for blowing the slider 74 to the second position through the second pneumatic pipeline 76. Specifically, first, food pills 4 are replenished in the upper conveying tube 72 through the food pill delivery port 721, and gas is delivered into the upper conveying tube 72 by the gas source 77 to drive the food pills 4 in the upper conveying tube 72 to move into the delivery box 71. Since the spiral coil section 722 is provided, the spiral coil section 722 can be used to store the food pills 4, thereby increasing the number of food pills 4 that can be stored in the upper conveying tube 72 and reducing the frequency of replenishing the food pills 4 in the upper conveying tube 72. Then, gas is delivered into the first pneumatic pipeline 75 by the gas source 77 to drive the slider 74 to move to the first position, so that the food pills in the upper conveying tube 72 can fall into the food pill passing port 741. Finally, gas is delivered into the second pneumatic pipeline 76 by the gas source 77 to drive the slider 74 to move to the second position, so that the food pills 4 in the food pill passing port 741 can fall into the lower conveying tube 73, thereby delivering the food pills 4 into the food trough 60 through the lower conveying tube 73. Thus, the food pills 4 can be pneumatically driven by the upper conveying tube 72 , and the timing of releasing the food pills 4 can be controlled by the first pneumatic pipeline 75 and the second pneumatic pipeline 76 , thereby achieving reliable release of the food pills 4 .

[0053] Further, the upper delivery pipe 72 and the lower delivery pipe 73 can be plastic pipes compared to the first pneumatic pipeline 75 and the second pneumatic pipeline 76. The upper delivery pipe 72 and the lower delivery pipe 73 can be thicker than the first pneumatic pipeline 75 and the second pneumatic pipeline 76. The air source 77 can be an air pump, and the upper delivery pipe 72, the first pneumatic pipeline 75 and the second pneumatic pipeline 76 are connected to the air pump through an electromagnetic switching valve. Thus, the pipeline for the air pump to deliver gas can be controlled by the electromagnetic switching valve, thereby realizing pneumatic control of the pneumatic food delivery device 70. The upper delivery pipe 72, the first pneumatic pipeline 75 and the second pneumatic pipeline 76 can also be connected with a pressure regulating valve for ensuring the stability of the airflow and the movement of the food pills, and a regulating valve for adjusting the size of the airflow.

[0054] The slider 74 can be made of polyoxymethylene material, which can provide the slider 74 with good self-lubricating properties, so that the slider 74 can slide more smoothly.

[0055] Advantageously, the primate behavior testing device 1 suitable for microwave exposure environment further comprises a delivery detection device, a delivery detection transmitting optical fiber, and a delivery detection receiving optical fiber.

[0056] The delivery detection device is arranged in the control end 10. One end of the delivery detection transmitting optical fiber is connected to the delivery detection device and has a delivery detection transmitting end. One end of the delivery detection receiving optical fiber is connected to the delivery detection device and has a delivery detection receiving end. The delivery detection transmitting end and the delivery detection receiving end are both connected to the lower conveying pipe 73 and arranged opposite to each other. In this way, when the food pill 4 passes through the lower conveying pipe 73, the delivery detection transmitting end and the delivery detection receiving end will be blocked, so that the light emitted by the delivery detection transmitting end cannot be received by the delivery detection receiving end, so that it can be judged whether the food pill 4 passes through the lower conveying pipe 73 through the receiving situation of the delivery detection receiving end, and it can be judged whether the food pill 4 is reliably delivered.

[0057] Figure 2 FIG. 1 shows a primate behavior testing device 1 suitable for a microwave exposure environment according to some examples of the present invention. Figure 2 As shown, the primate behavior testing device 1 suitable for microwave exposure environment also includes a height-adjustable lifting base 90, on which the operation terminal 20 is arranged, and a handle 91 is arranged on the lifting base 90. In this way, the height of the operation terminal 20 can be easily adjusted through the lifting base 90 to be suitable for primates 3 of different heights, further improving the applicability of the primate behavior testing device 1 suitable for microwave exposure environment, and the handle 91 can facilitate the transportation of the primate behavior testing device 1 suitable for microwave exposure environment.

[0058] Optionally, the height adjustment range of the lifting base 90 is 10 cm-30 cm.

[0059] Advantageously, if Figure 2 As shown, the primate behavior testing device 1 suitable for microwave exposure environment further includes a connecting arm 81, the two ends of which are respectively connected to the operation terminal 20 and the fixed chair 80, and the rotation axis is oriented in the horizontal direction. In this way, the fixed chair 80 can be positioned by using the connecting arm 81 to prevent the fixed chair 80 from shifting or tipping over, and the height adjustment of the operation terminal 20 can be facilitated by the rotation of the connecting arm 81.

[0060] More advantageously, a buffer pad for buffering the food balls is provided in the food trough 60. Specifically, the food trough 60 may be bowl-shaped, and the buffer pad may be a flexible pad to reduce the probability of the food balls 4 falling out of the food trough 60 after collision.

[0061] Specifically, the assembly of the operation terminal 20 and the connection of various structures thereon can be performed using polyamide (PA) screws.

[0062] Figure 1 FIG. 1 shows a primate behavior testing device 1 suitable for a microwave exposure environment according to some examples of the present invention. Figure 1 As shown, the primate behavior testing device 1 suitable for microwave exposure environment also includes a display control panel 11, which is arranged on the control terminal 10. In this way, the primate behavior testing device 1 suitable for microwave exposure environment can be controlled by the display control panel 11, and the test results can be displayed, which is convenient for operators to observe.

[0063] Specifically, the primate 3 may be a macaque.

[0064] The display and control panel 11 can have a built-in control program for setting the behavioral task program, receiving the detection results of the press detection device 50, controlling the different colors of light that provide visual stimulation in the behavioral task and the pneumatic force for controlling the delivery of food pellets as rewards, and realizing the connection between the various modules of the primate behavior testing device 1 suitable for a microwave exposure environment.

[0065] The display control panel 11 can adopt an embedded microcontroller system, have a human-computer interaction interface, set the software program for implementing different behavioral tasks, and record experimental data. The main interface of the human-computer interaction interface can display the lighting status of the five buttons and the progress of the experimental task, and control the experimental process through the "start", "end" and "pause" options.

[0066] The human-computer interaction interface can also enter the program setting interface through the "Settings" option, including three task programs: feeding learning, pressing learning and DMTS task:

[0067] For food-taking learning, fixed or random intervals can be set to automatically release food pellets, so that the macaques feel close to the device, stimulate their motivation, and learn to get food from the device. Pressing learning can be based on the principle of operant conditioning, and the purpose is to let the macaques learn to press the lighted button to get a food pellet reward. The DMTS task can be used for macaques to learn the principle of DMTS tasks and conduct behavioral tests. According to the principle of DMTS tasks, one of the five light-transmitting buttons (for example, the light-transmitting button in the middle) is preset as the sample light button. The task steps are: first, the sample light button presents a color. After the macaque makes a pressing response, it enters a delay period, during which the color needs to be memorized. After the delay period, the remaining four buttons present different colors, one of which is the same color as the sample light button. If the macaque presses it, it will be rewarded with food, and if it is wrong, there will be no reward. In the basic settings, parameters such as the light stimulus presentation time and the length of the delay period can be adjusted. In the pressing learning and DMTS tasks, each button can be set separately. You can select the number of buttons to use. Click the button icon to enter the button color setting interface. By selecting whether to use the button and the color to use, you can flexibly adjust the difficulty of the task. In the prompt sound setting interface, you can check whether to give a prompt sound for each step of the task.

[0068] The main interface of the human-computer interaction interface can also view the data through the "Data" option. The control terminal 10 is provided with a USB data export interface for inserting an external U disk. The experimental data can be directly entered into the U disk, including information on each step of the behavioral task, such as reaction time, correctness, color, etc., for further detailed analysis.
