NEUROPSYCHOLOGICAL SPATIOTEMPORAL PATTERN RECOGNITION
First Claim
1. A method for establishing a knowledge base of neuropsychological flow patterns, the method comprising:
- obtaining signals from multiple subjects from one or more research groups for a particular behavioral process, wherein said signals comprise EEG signals;
determining source localization participating in said particular behavioral process for said research groups according to said signals;
identifying sets of patterns of brain activity for said behavioral process for said research groups;
neuropsychologically analyzing said source localization and said identified patterns for each of said research groups, said neuropsychologically analyzing comprising;
identifying a plurality of possible pathways for said identified sets of patterns;
ranking said possible pathways based on likelihood for said particular behavioral process; and
reducing the number of ranked possible pathways based on one or more additional constraints;
creating a set of flow patterns from said neuropsychologically analyzed sources and patterns, for each of said research groups; and
creating a knowledge base of said flow patterns, wherein said knowledge base is then used as a constraint for said reducing.

Abstract
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.
