Fig. 4 illustrates a flow chart of an infrared beam positioning method, which, as shown in fig. 4, comprises the steps of:
the infrared light source 100 emits an infrared light beam to the light beam shaping module 200, and the light beam shaping module 200 performs spot shaping, collimated light beam and spot reduction processing on the infrared light beam;
transmitting the infrared light beam processed by the beam shaping module 200 to the focusing module 300, and transmitting the received infrared light beam into the optical fiber 400 after the focusing module 300 focuses the received infrared light beam;
the optical fiber 400 is arranged on the side surface of the climbing device 500 with a set slope angle and is inserted into the sleeve 600;
the emitting end of the optical fiber 400 is guided to the corresponding target zone through the ferrule 600, and the infrared beam emitted through the optical fiber 400 stimulates the target zone.
Specifically, an infrared beam with a wavelength of 4.7 μm to 4.9 μm, a repetition frequency of 45kHz and a pulse width of 2us is emitted to the beam shaping module 200 by the frequency-modulated infrared light source 100;
the beam shaping module 200 is used for carrying out spot shaping, beam collimating and spot reducing on the initial infrared beam, so that the spot diameter of the shaped infrared beam is smaller than 200 mu m;
converging the energy of the shaped infrared beam through a focusing module 300 to enable the spot diameter of the focused infrared beam to be less than or equal to 20 microns and the power to be 0.1-1 mW;
the focused infrared light beams are transmitted through the optical fiber 400, the optical fiber 400 is fixed on the slope of the climbing device 500 and finally penetrates into the casing 600, and the exit end of the optical fiber 400 is close to but not exposed at the second end of the casing 600;
the helmet 700 is worn on the head of an acting object, the outgoing end of the optical fiber 400 is guided to a target area, namely a hippocampus CA3 area, the hippocampus CA3a subregion is stimulated for 10min, and then the hippocampus CA3b subregion is stimulated for 10min, so that the parameters of infrared beams stimulated twice are consistent.
The infrared beam positioning device of the present embodiment can be applied to improve the learning memory, and the infrared beam positioning device is described in detail below to improve the learning memory. The experiment of 12 male C57 mice of 6-8 weeks old based on the infrared beam positioning method provided by the invention is as follows:
randomly selecting 12C 57 mice with similar physiological state (such as size, weight, etc.) at 6-8 weeks, and dividing into two groups, namely a control group and a deal group. The brain stereotaxic apparatus is combined with a mouse brain atlas to carry out craniotomy, embedding sleeve and other brain operations on all mice, and the position determination of the optical fiber is completed. Wherein the control group was used as a control group without any irradiation stimulation, the Traet group was irradiated with 4.8 μm infrared beams, and the mouse hippocampus CA3 area was irradiated with irradiation stimulation in turns for 10min on each side.
After irradiation, the Y maze was performed separately for each animal. The Y maze experiment is provided with 3 arms in total, the initial arm is the first arm, the other arms are the second arm, the new different arm is the third arm, and the difference of the internal environments of the three arms is only in the visual clues on the inner side surfaces of the arms, so that the memory of the mouse through transferring the visual clues is helped to further identify which arm is the new arm. The mouse is placed in the cage from the initial arm (arm one), the new different arm (arm three) is shielded, the initial arm (arm one) and the other arm (arm two) are freely explored for 10min, after exploration is finished, the mouse is placed back into the cage to be raised, and the labyrinth is cleaned by alcohol in the free exploration process of the mouse, so that the influence of smell on an experimental result is eliminated. After 1 hour of the learning phase, open the blocked new arm (arm three), place the mouse from the starting arm (arm one), let it explore freely for 5min, record the ratio of the time the mouse entered the new arm (arm three) to the time it entered the full exploration. The mean value of each group of mice was calculated as the mean ± sem, and the ratio of time to enter all arms was plotted against the data. The Y maze result shows that the infrared stimulation of the CA3 area of the hippocampus brain area can promote the mouse to enter the three new different arms to account for the proportion of the total time, namely the infrared stimulation of the CA3 area of the hippocampus brain area can promote the mouse to identify the three new different arms by improving the memory capacity of the mouse, and further promote the relative time for exploring the three arms, which shows that the infrared stimulation of specific parameters in the specific brain area has obvious effect on improving the learning and memory capacity of the mouse.
After the experiment was completed, the mice were further tested for neoformant identification. The mouse is placed into the experiment box from the center of the experiment box to freely explore for 10min, and after the experiment box is finished, the experiment box is wiped by alcohol to avoid the influence of smell on the experiment result. After 24 hours apart, two objects a and B of the same shape (round wood blocks) were placed in the laboratory box at a distance of at least 5cm from the box arm to ensure the mouse was free to pass through and the mouse was freely explored 10min by placing the mouse head towards the box arm. And finally, changing A of A, B two objects into a new object C (square wood block) and placing the new object C at the position of the original A. The mouse was placed into the box from the same position with its head towards the arm of the box and allowed to freely explore again for 10 min. The discrimination coefficients explored by the mice were recorded. The calculation method is that the time for contacting (including smelling and touching) the new object is T1, the time for searching the old object is T2, and the total search time T of the mouse is T1+ T2. When the absolute identification is defined as E, E is T1-T2. And D is defined as the identification coefficient, and D is E/T. And (5) calculating the average value of each group of mice, calculating the result as the average value +/-standard error, counting the result and drawing. The new object identification result shows that the infrared stimulation of the CA3 area of the hippocampal brain area can promote the identification coefficient of the mouse to be increased, and prompts the mouse to improve the identification of the new and different objects, which indicates that the improvement of the memory capacity of the mouse by the infrared stimulation of the CA3 area can promote the mouse to better identify the square wood block as the new and different object in the environment, increase the exploration contact time of the square wood block, and finally improve the identification coefficient value. The pathway exploration plot shows that the infrared stimulated group of mice in the CA3 region had significantly increased exploratory exposure to the shaped wood blocks (squares) compared to the control group of mice.
Through statistical analysis of the two behavioral indexes, the mice in the control group (without infrared stimulation) can be found, the exploration ratio and time of the mice in the infrared light stimulation group given with specific parameters to the neobrachium and the neoforeign object are obviously increased, and the specific parameter infrared irradiation stimulation in the hippocampal CA3 area has certain promotion and improvement effects on the cognitive function of the mice, especially on the learning and memory ability.
