This study explores the analysis of EEG signals to understand brain microstates and their dynamics in schizophrenia. Key aspects include:
-
Transition Matrix and Graphs: Creation of transition matrices and directed graphs to quantify and visualize EEG-derived microstate transitions in individuals with schizophrenia and healthy controls.
-
Motif Analysis: Identification of recurring microstate transition patterns (motifs) within the complex networks, offering insights into neural circuitry differences in schizophrenia.
-
Comparative Analysis: Utilization of statistical methods to compare motif distributions between groups, highlighting motifs that significantly differ in schizophrenia.
-
Implications: The study discusses how certain EEG microstate motifs could serve as potential biomarkers for schizophrenia, aiding in diagnostics and therapeutic strategies.
This research integrates statistical techniques and graph theory.
