Brain power source imaging method and device, equipment, storage medium and program product

Abstract

The invention relates to the technical field of electroencephalogram signals, and discloses an electroencephalogram imaging method, device and equipment, a storage medium and a program product. Preprocessing the electroencephalogram signal data; the preprocessed electroencephalogram signal data are input into a pre-constructed feature extraction model, a cerebral cortex electrical activity reconstruction result is output, and the cerebral cortex electrical activity reconstruction result is used for electroencephalogram source imaging; the feature extraction model comprises an adaptive weight space mapping module and a space extraction module; wherein the adaptive weight space mapping module is used for mapping a measurement space to a source space to obtain a source space feature map; the space extraction module is used for extracting cerebral cortex time sequence features based on the source space feature map. According to the brain power supply imaging method provided by the invention, the feature information of the space dimension and the time dimension is fully utilized, and the high-precision reconstruction of the electrical activity of the cerebral cortex is realized.
