[0002] The knowledge of neurosurgeons in most hospitals in my country on the location of the brain's language function area comes from Western scholars' research on Western languages ​​over the past 100 years, and Chinese language is significantly different from other Western languages ​​such as English. Studies have found that the processing of Chinese and Western languages ​​involves several common brain areas, including the left inferior frontal gyrus, the left temporal occipital area, and the left middle and superior temporal gyrus. However, the processing of Chinese language also includes the left middle frontal gyrus, the left superior parietal gyrus, and the right middle and superior temporal gyrus, which are not required for Western language processing. Therefore, for people who use Chinese as their daily communication language, if the language function area of ​​the brain is located only based on traditional anatomical structures and classic language function area models, it will be easy to cause iatrogenic damage to the language function area due to inaccurate positioning. Therefore, how to efficiently and accurately locate the language function area of ​​the brain has become a problem that needs to be solved urgently. Utility Model Content

[0027] The optical laser assembly 5 includes a protective shell 501, a light source controller 502, an illumination mirror 503 and a shading plate 504. The top of the protective shell 501 is bolted to the bottom of the electric push rod 4, the light source controller 502 is bolted to the front side of the protective shell 501, the light source controller 502 is electrically connected to the control host 1, the illumination mirror 503 is arranged on the rear side of the light source controller 502, and the shading plate 504 is bolted to the top and bottom of the protective shell 501 respectively.

[0028] The broadcasting component 6 includes a fixed block 601, a rotating sleeve 602 and a broadcasting earmuff 603. The fixed block 601 is bolted to both sides of the head cover 2 respectively, the rotating sleeve 602 is rotatably connected to the bottom of the fixed block 601, the broadcasting earmuff 603 is bolted to the bottom of the rotating sleeve 602, and the broadcasting earmuff 603 is electrically connected to the control host 1.

[0029] In the technical solution of the utility model, a control host 1, a head cover 2, a magnetic stimulation coil 3, an electric push rod 4, a light excitation component 5 and a broadcasting component 6 are arranged, and the control host 1 is connected to the head cover 2 by using a powered data line, and then the head cover 2 is put on the head of the patient with brain dysfunction who needs to be treated. In this process, the broadcasting earmuffs 603 are rotated to drive the rotating sleeve 602 to rotate at the bottom of its fixed block 601, so as to adjust the broadcasting earmuffs 603 so that they are put on the patient's ears, and then the control host 1 starts the electric push rods 4 on both sides of the top of the head cover 2 to push the protective shell 501 downward, so that the light mirror 503 located inside the protective shell 501 is located directly in front of the patient's eyes, and then the user controls the control host 1 to start The magnetic stimulation coil 3 inside the headgear 2 is turned on to achieve transcranial magnetic stimulation of the patient's brain, so as to use the changing magnetic field to generate induced current in the brain, thereby regulating the neural activity of the cerebral cortex, thereby helping the patient to restore damaged neural conduction, and synchronously controlling the control host 1 to turn on the light source controller 502 located inside the protective shell 501 to prepare the intensity and flickering frequency of the light source, and then irradiate the patient's eye visual nerve through the illumination mirror 503, so as to synchronously re-stimulate and activate the brain nerve cells, thereby strengthening the patient's brain function positioning test under the synchronous operation of its light stimulation treatment and transcranial magnetism, and at the same time, the broadcasting earmuffs 603 are turned on through the control host 1 to play the Chinese language test and generate a language evaluation report for the tested individual.

[0030] Among them, a Chinese test can be first performed on patients with brain diseases. By performing a Chinese test on patients, a general understanding of the patient's language ability can be obtained. The patient's language test results are used to generate a test report so that the system can formulate a personalized language stimulation task plan for the patient. The personalized language stimulation task plan can include various levels of Chinese processing (synonym judgment, homophonic judgment, rhyme judgment, Chinese character naming, sentence comprehension, and picture naming). This embodiment of the application is not limited.

[0031] It is also possible to develop personalized language stimulation tasks for patients, such as the type of task, task duration, patient response mode, etc.; based on the patient's personal information, the specific implementation methods for developing personalized language stimulation task plans for patients are as follows: sentence comprehension tasks can be selected; different types of materials can be selected based on different cultural levels, such as allowing educated people to choose language materials for experimental tasks, while uneducated people can choose picture materials for experimental tasks; experimental tasks of different difficulty levels can be selected based on the age of the patient. If the patient is a child, the interval time after the stimulus presentation can be appropriately lengthened compared to adults, so that the patient has a longer reaction time.

[0032] Specifically, an example is given to illustrate the implementation of the language stimulation task. For example, in a reading function task, the display screen presents two Chinese characters arranged vertically, and the tested individual is required to judge whether the pronunciations are the same. If they are the same, the right hand (index finger) presses a button; if they are different, the left hand (index finger) presses a button; if the control condition is a font size judgment task, the display screen presents two Chinese characters arranged vertically, and the tested individual is required to judge whether the font sizes are the same. If they are the same, the right hand (index finger) presses a button; if they are different, the left hand (index finger) presses a button;

[0033] Once a personalized language stimulation task plan is developed for the patient, the corresponding language stimulation materials can be selected from the stimulation corpus and output, and the language stimulation materials can be displayed on the screen of an electronic device for the patient to watch and better perform the language stimulation task.

[0034] Specifically, a mask of the patient's injury site is first constructed to avoid interference of the patient's brain injury deformation on the data processing process; then the MRI data is preprocessed, including time correction, head motion correction, spatial normalization and spatial smoothing to correct the time and space errors in the scanning process; the preprocessed MRI data is the MRI data after the original MRI data is converted into a processable NIfTI format using SPM (http: / / www.fil.ion.ucl.ac.uk / spm / ) data processing software; after the MRI data preprocessing is completed, the generalized linear model (GLM) is used linearmodel), statistical analysis of MRI image data at the individual level was performed; based on the design of different tasks, a regression model was established, and the scanning head movement parameters were included in the statistical model as covariates to control the influence of head movement on the localization of language function areas; finally, a single-sample t-test was used to generate t-value graphs of different levels or types of language processing; functional MRI image visualization software such as SPM, mricro, xjview, mango, brainnetreview, etc. were used to present activation maps with different statistical thresholds, and the localization map of the patient's brain language function area was obtained.

[0035] In the present application, a personalized language stimulation task plan can be formulated for patients with brain diseases. When the patient performs the language stimulation task, a magnetic resonance scan of the patient's head can be performed, and a localization map of the patient's brain language function area can be obtained by analyzing and processing the image data of the magnetic resonance scan. This is of great help in protecting the patient's language function and improving the quality of life.
