Embodiment Construction

[0017] The EEG real-time detection and analysis platform based on the microstate analysis method of the present invention is described in conjunction with the accompanying drawings.

[0018] The design idea of ​​the EEG real-time detection and analysis platform based on the micro-state analysis method of the present invention is to firstly control the ADC module 4 to use the EEG electrode array 1 to collect EEG signals through the human-computer interaction interface 18 in the host computer 3, and the collected EEG signals The physiological signal is subjected to preprocessing steps such as denoising and filtering on the original EEG electrophysiological signal through the EEG preprocessing module 7 in the DSP operation chip 5, and obtains an EEG time series 10 that removes noise interference and a rhythm that can be used for research and analysis; The final EEG signal 10 is input to the microstate analysis module 11 in the DSP operation chip 5 to carry out microstate analysis;...

Abstract

The invention relates to a microstate analysis method based EEG real-time detection and analysis platform. The platform includes an EEG electrode array (1) used for collecting scalp electroencephalogram, a slave computer (2) used for scalp electroencephalogram acquisition, preprocessing and microstate analysis and a host computer (3) for displaying analyzed results; the slave computer (2) includesan ADC module (4), a DSP operation chip (5) and a USB communication module (6); the EEG electrode array (1) and the ADC module (4) collect scalp electroencephalogram signals; an EEG preprocessing module (7) in the DSP operation chip (5) preprocesses an original EEG signal, so that a clean EEG signal (10) for analysis can be obtained; and the preprocessed EEG signal is input to a microstate analysis module (11) to carry out further analysis and processing so as to obtain the analyzed results and specific characteristic parameters.

Description

technical field [0001] The invention relates to biomedical engineering technology, in particular to an EEG real-time detection and analysis platform based on a microstate analysis method. Background technique [0002] Parkinson's disease is a neurological disease characterized by neurodegenerative changes, and its clinical symptoms usually manifest as severe movement disorders such as resting tremor, muscle rigidity, slowness of movement, and postural imbalance. The incidence of Parkinson's disease is as high as 26% among people over 60 years old, and it will further worsen with the prolongation of the disease course, eventually leading to the loss of self-care ability and even disability. Therefore, an efficient real-time auxiliary diagnostic tool will be of great significance to the treatment of patients with Parkinson's disease. Scalp EEG microstate analysis method is an effective method for diagnosing neurological diseases (such as Parkinson's disease, epilepsy, etc.). ...
