[0049] Other features, objects and advantages of the present invention will become more apparent upon reading the detailed description of non-limiting embodiments with reference to the following drawings:
[0050] Figure 1 This is a schematic diagram of the vibration stimulation module structure;
[0051] Figure 2 Flowchart of the process of vibration stimulation regulating brain function and regulatory effectiveness evaluation. DETAILED DESCRIPTION
[0052] The present invention will be described in detail below with reference to specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those skilled in the art, several changes and improvements can be made without departing from the scope of the present invention. These all fall within the scope of protection of the present invention.
[0053] Example 1
[0054] The present invention provides a method for regulating brain function through vibration stimulation, comprising: step 1: designing and developing a vibration stimulation module suitable for the head using the principle of electromagnetic induction, which includes a signal generator, a power amplifier, and a vibration plate; step 2: placing the vibration stimulation module under the neck, turning on the vibration stimulation module, and adjusting the appropriate vibration amplitude and vibration frequency; step 3: setting the vibration duration to vibrate and obtain functional magnetic resonance (FMR) data; step 4: if it is necessary to evaluate the effectiveness of the vibration, a functional magnetic resonance (FMR) sequence can be used to scan before and after the vibration, and the functional magnetic resonance (FMR) data obtained in step 3 can be processed and analyzed to obtain a low-frequency fluctuation amplitude image that can represent spontaneous brain activity, as well as a coupling of whole-brain gray matter signals and cerebrospinal fluid signals.
[0055] The processing and analysis process of functional magnetic resonance imaging data is as follows:
[0056] 1. Time layer calibration: Select the middle layer as the reference layer and calibrate the time data of other layers to eliminate the time difference between layers caused by inconsistent scanning intervals.
[0057] 2. Head Motion Correction: A six-parameter rigid linear transformation model was applied to correct the images at each time point to align them with the initial time point image. This minimizes the effect of slight head movement during scanning. Data from subjects with head motion parameters exceeding 3mm in displacement or 3 degrees in rotation were removed.
[0058] 3. Spatial registration: First, the functional image is registered with the structural image, and then the structural image is calibrated to the Montreal Neurological Institute standard brain space. Next, the functional image is spatially registered according to the standardized parameters of the structural image, and the voxel resolution of the functional image is adjusted to 3×3×3mm 3 .
[0059] 4. Spatial smoothing: The spatially registered functional images were spatially smoothed using a Gaussian kernel of 4 mm full width at half maximum.
[0060] 5. Calculate the low-frequency fluctuation amplitude of the whole brain and extract the gray matter signal and cerebrospinal fluid signal of the whole brain.
[0061] 6. Use the two-sample t-test to perform statistical analysis on the amplitude of low-frequency fluctuations in the whole brain before and after vibration, as well as the coupling between the whole-brain gray matter signal and the cerebrospinal fluid signal.
[0062] The step 1 includes the following steps: Step 1.1: The signal generator in the vibration stimulation module is responsible for generating electrical signals of specific frequency and amplitude. These signals will be used to control the vibration of the vibration plate. It is necessary to be able to generate stable sine waves, square waves or other specific waveform signals to meet different stimulation needs. Step 1.2: A high-efficiency, low-distortion and wide-bandwidth power amplifier is used to amplify the low-power signal generated by the signal generator to a rated power that can drive the vibration plate module to start working, so as to ensure the integrity of the signal and the accuracy of the vibration. Step 1.3: The vibration plate module is the part that directly contacts the skin and generates vibration stimulation. A light, flexible vibration plate that can generate sufficient amplitude and frequency range is used. Step 1.4: Integrate the signal generator, power amplifier and vibration plate module into a complete system.
[0063] like Figure 1 The function of the vibration plate module is to receive the signal transmitted by the power amplifier and generate vibration of corresponding frequency and amplitude. The data transmission direction is: signal generator → power amplifier → vibration plate module → human body.
[0064] The step 2 includes the following steps: Step 2.1: Ensure that the vibration stimulation module has been completed in accordance with the design and development requirements in step 1, and conduct a safety and biocompatibility assessment. Step 2.2: Place the vibration stimulation module tested in step 2.1 under the user's neck, ensuring that the vibration plate is in good contact with the skin and is not blocked by clothing or other obstacles. Step 2.3: Turn on the power of the vibration module, set the vibration frequency to 40Hz, and set the vibration amplitude to 2mm. Step 2.4: During the vibration stimulation process in step 2.3, closely observe the user's reaction and ask whether he feels uncomfortable or has other adverse reactions. If the user reports discomfort, the vibration parameters should be adjusted immediately or the stimulation should be paused to ensure the safety and comfort of the user.
[0065] The step 3 includes the following steps: setting the vibration duration of the vibration stimulation module to 5 minutes to ensure the continuity and consistency of the vibration stimulation.
[0066] like Figure 2, step 4 includes the following steps: Step 4.1: If the effectiveness of vibration needs to be evaluated, make sure that the magnetic resonance equipment has been calibrated and is ready for scanning. Before applying vibration stimulation, first perform a functional magnetic resonance imaging (fMRI) scan on the user to obtain baseline data. This will serve as a reference point for comparing changes in brain activity after vibration stimulation. Step 4.2: Using the vibration stimulation module constructed in step 2, place the module under the subject's neck, turn on the vibration module, and adjust to the appropriate vibration amplitude and frequency. Step 4.3: Immediately after the vibration stimulation ends, perform a second functional magnetic resonance imaging (fMRI) scan. This scan will capture changes in brain activity after vibration stimulation, compare it with the baseline data before vibration, and evaluate the effectiveness of vibration stimulation, that is, calculate the amplitude of low-frequency fluctuations in the brain's spontaneous brain activity to determine whether there are changes before and after vibration.
[0067] Step 4.4: Process and analyze the functional magnetic resonance imaging data obtained in step 3 to obtain low-frequency fluctuation amplitude images that can represent spontaneous brain activity and the coupling of whole-brain gray matter signals and cerebrospinal fluid signals.
