神経生理学的データの重み付き分析のための方法およびシステム
Document Type and Number:
Japanese Patent JP6401893
Kind Code:
B2
Abstract:
A method and system for analyzing neurophysiological data, the neurophysiological data being electroencephalogram (EEG) data collected using a plurality of measuring devices respectively placed at a plurality of different locations on the scalp of a subject, the method comprising:using a data processor for:applying multidimensional analysis to the data to extract spatial and non-spatial characteristics of the data, said spatial characteristics describing locations from which the respective data were acquired, and said non-spatial characteristics being obtained by segmenting the data according to the time of acquisition and by performing waveform analysis and extracting waveform characteristics;defining a plurality of vectors, each including, as components of said vector, said spatial characteristics, and one or more non-spatial characteristics as obtained from said segmentation and said decomposition, thereby providing a plurality of features of the data, each feature being a vector of said plurality of vectors;constructing a brain network activity (BNA) pattern having a plurality of nodes, each representing a cluster of vectors of data characteristics;assigning a connectivity weight to each pair of nodes in said BNA pattern; andtransmitting said BNA pattern to a display device or computer-readable medium;wherein said connectivity weight comprises a weight index calculated based on at least one cluster property selected from the group consisting of: (i) a number of vectors in a corresponding pair of clusters; (ii) a variability among numbers of vectors in said corresponding pair of clusters; (iii) a width of time windows (ΔtA, ΔtB,) associated with each cluster of said corresponding pair of clusters; (iv) a latency difference (ΔtAB) separating said corresponding pair of clusters.
