Description
Technical Field
The invention relates to a biomedical engineering technology, in particular to an EEG real-time detection and analysis platform based on a micro-state analysis method.
Background
Parkinson's disease is a nervous system disease characterized mainly by neurodegenerative diseases, and clinical symptoms usually manifest as severe dyskinesia such as resting tremor, muscular rigidity, bradykinesia, and postural imbalance of patients. The incidence of parkinson's disease is as high as 26% in people over the age of 60 and will further worsen with the course of the disease, eventually leading to the loss of self-care and even disability of the patient. Therefore, the efficient real-time auxiliary diagnostic tool has great significance for treating the Parkinson disease patient. The scalp electroencephalogram micro-state analysis method is an effective means for diagnosing nervous system diseases (such as Parkinson's disease, epilepsy and the like) at present. The presence of a particular micro-condition and its change in frequency, coverage or duration of occurrence can be considered a characteristic status marker for different neurological conditions as an effective diagnostic aid.
The electroencephalogram micro-state analysis method is provided based on electroencephalogram micro-states and is used for analyzing the dynamic change of a global mode of a scalp potential topological structure along with time. The scalp potential topological structure can describe the dynamic change of brain activity in a resting state, and the research range of EEG in the field of researching neuropsychiatric diseases is widened. The microstate analysis method can reflect the change condition of the functional network of the brain in the resting state, the microstate obtained by the analysis method can explain 90% of the dynamic change of the brain, and the mutual conversion among several microstate can reveal the dynamic change of the brain activity in the level of sub-second individual, and has the advantages of strong operability, strong representation individual specificity, strong robustness and the like.
At present, there is no monitoring device integrating EEG acquisition and analysis, and there is a time delay in the mechanism of analyzing neuropsychiatric diseases through EEG signals, i.e. the analysis result can only reflect the state of illness at the moment of acquiring EEG signals, and there is no direct connection with the current state of illness development. The current microstate analysis method for EEG signals, although it can significantly describe the brain activity characteristics of parkinson's disease, cannot be used as a practical tool for clinical diagnosis because it cannot provide clinically-referable real-time information for the auxiliary diagnosis of diseases. Therefore, a set of real-time detection and analysis platform capable of simultaneously controlling signal acquisition and signal analysis is established, so that the acquisition and analysis of EEG signals are synchronously carried out, and the condition of the Parkinson patients is reflected in the future development direction in a real-time, efficient and visual manner.
A Digital Signal Processor (DSP) is a microprocessor commonly used for Digital Signal processing operations, and has the advantages of high precision, good stability, high speed, high integration level, and the like, so that the DSP processor has significant advantages in the data processing and analyzing processes. The DSP processor is combined with the preprocessing process and the micro-state analysis method of the EEG signal, so that the EEG signal acquisition and high-speed data processing capability is realized, and the effect of efficiently detecting and analyzing the EEG information in real time is achieved.

The EEG electrode array 1 and the ADC module 4 realize the collection of scalp brain electrical signals; an EEG preprocessing module 7 in the DSP operation chip 5 performs a preprocessing process on the original EEG signal so as to obtain a clean EEG signal 10 for analysis; inputting the preprocessed EEG signal into a micro-state analysis module 11 and further analyzing and processing the EEG signal to obtain an analysis result and specific characteristic parameters; the real-time human-computer interaction interface 18 of the upper computer 3 is realized by VB programming, and the data communication between the upper computer 3 and the DSP operation chip 5 is realized by the USB communication module 6.

The micro-state analysis module 11 comprises a GFP calculation and preprocessing module 12, an improved K-means clustering algorithm module 13, a micro-state reverse coupling module 14 and a micro-state feature parameter extraction module 15. The modules are modules with algorithm realization functions, are realized by C + + compiling and downloaded to the DSP operation chip 9 to realize the data analysis and processing functions in the step.
The micro-state analysis module 11 is a core component of the platform for analyzing and processing the EEG signals, and has a function of analyzing the micro-state of the EEG signals acquired in real time. The GFP calculation and preprocessing module 12 calculates the global field power time series GFP as the spatial standard deviation of the electroencephalogram topographic map at each given time. At the local GFP maxima, the brain electrical has the greatest signal-to-noise ratio, the spatial configuration at that time is considered stable, and the topographic map at the GFP maxima has a similar topology to the topographic map between its adjacent GFP maxima. Therefore, the electroencephalographic maps at all maxima of GFP were obtained and used to calculate the overall microstate structure. The improved K-means clustering algorithm module 13 is used for clustering and calculating all topographic maps formed by signals at all GFP maximum points by using an improved K-means clustering algorithm to obtain individual micro-state classes. The micro-state back-coupling module 14 marks the electroencephalogram topographic map of the entire EEG signal using the obtained micro-state as a mark template, and marks the topographic map at all times as a specific one of the micro-state classes. The micro-state characteristic parameter extraction module 15 performs statistical calculation on the results of the above processes to obtain characteristic parameters such as average duration, occurrence frequency per second, total coverage rate and transition probability between micro-state classes of each micro-state class, so as to describe abnormal brain activity and stable state of illness.
