腦電數(shù)據(jù)處理軟件中關(guān)鍵算法的實(shí)現(xiàn)
[Abstract]:The brain is the core of the body. In order to study brain function, we introduced Electroencephalogram,EEG. EEG maps the state and activity of the body. Different positions on the scalp produce different physiological signals as a result of changes and movements in the body, which are called EEG signals. All leads show EEG, showing the pattern of brain activity. In order to study EEG signals, many algorithms have been developed in our laboratory, which have accumulated and precipitated for more than ten years. There have been several kinds of EEG processing software in the world, which has played a great role in the research of EEG in the world, but the price is not cheap, and the data format is different, so the signals processed by the software can not communicate. Based on the lack of EEG software in China, we put the experimental algorithms such as eye electrical artifacts removal, source location and unique zero reference (ReferenceElectrodeStandardizationTechnique,REST) into the EEG analysis and processing software. In order to be used by a large number of experimental institutions engaged in EEG industry in China, we have concentrated the data format of current mainstream EEG software in our software and hope to play a promoting role in the international market. The work of this paper mainly comes from the software project of three years graduate student period, this software carries on the function extension and consummation on the basis of the original frame, the extended function mainly has the REST function, The reading and storage of various data formats and the conversion between them, the reading and matching of electrode and the reading and coordinate matching of LORETA head model slices, the filtering function of PCA, the removal of eye electrical artifacts, the multithread function, etc. At the same time, in order to meet the needs of scientific research in the laboratory, some practical software functions, such as data cutting function, have been developed to extract useful information from big data, such as batch processing. Batch reference conversion can be carried out, including any reference conversion function of REST. In order to verify the correctness of the function during the development process, the testing function is developed to ensure the quality of the software.
