Neuropsychological spatiotemporal pattern recognition

摘要

Systems and methods for identifying and analyzing neuropsychological flow patterns, include creating a knowledge base of neuropsychological flow patterns. The knowledge base is formed by obtaining signals from multiple research groups for particular behavioral processes, localizing sources of activity participating in the particular behavioral processes, identifying sets of patterns of brain activity for the behavioral processes and neuropsychologically analyzing the localized sources and the identified patterns for each of the research groups. The neuropsychological analysis includes identifying all possible pathways for the identified sets of patterns, ranking the possible pathways based on likelihood for the particular behavioral process and reducing the number of ranked possible pathways based on additional constraints. A system for comparison of obtained signals from an individual to the created knowledge base is provided. These obtained signals are then used to further update the existing knowledge base.

1. A method of constructing a flow pattern database, comprising:
obtaining EEG and/or MEG signals from multiple subjects from one or more research groups for a behavioral process; identifying brain activity patterns for said behavioral process for said research groups using a counting method or method of calculating statistical significances of pairs; identifying a plurality of candidate pathways for said brain activity patterns; for each research group, defining a set of flow patterns among functional brain regions based on said candidate pathways, thereby constructing the flow pattern database.
