EEG Connectivity Analysis
EEG Connectivity Analysis
Phase and connectivity analysis
This webinar provides an overview and the theoretical background of functional connectivity and phase analysis of EEG signals. The presentation guides you through basic methodology and important concepts, like synchronization and complex values. We demonstrate an exemplary connectivity workflow via Analyzer 2's Coherence and Correlation Measures transformations (available from version 2.2.0) as well as pipelines for well-known phase-based measures like Phase-Locking Value and Phase-Locking Factor. We discuss the interpretation of results and caveats that are common for EEG connectivity.
This webinar is intended for researchers who want to learn about connectivity analysis but are otherwise experienced in EEG processing and time-frequency domain analysis.
