Video Summary

The NANCE Education Committee webinar explored neural signal analysis using the EEG Lab Toolbox, emphasizing its significance in EEG research. İdnur Telkes and Lisa Goodman, the moderators, introduced Dr. Arnaud Delorme, a neuroscientist and chief architect of EEG Lab, highlighting his research in human consciousness and his contributions to EEG analysis. Dr. Delorme provided a historical overview of EEG, tracing its evolution from Hans Berger's invention in 1924 to modern developments, including the introduction of independent component analysis (ICA) and the EEG Lab software in 2003.<br /><br />Dr. Delorme explained EEG's clinical and research applications, focusing on event-related potentials (ERP) and spectral analysis to understand brainwave changes. He addressed the inverse problem in EEG, which involves deducing brain activity origins from scalp recordings, emphasizing the role of ICA in separating EEG sources more clearly.<br /><br />EEG Lab’s features were discussed in detail, showing its capabilities for data import, cleaning, ICA application, and source localization, supported by various plugins and extensions. The software's primary strength lies in its open-source nature and ability to perform group analyses, evidenced by its structured data management using the Brain Imaging Data Structure (BIDS). <br /><br />During the Q&A, challenges around EEG accuracy, especially in locating deep brain structures, and strategies for dealing with stimulation artifacts were discussed, reflecting on the complexities of integrating EEG with other modalities like fMRI. The session concluded with insights on starting EEG projects, emphasizing the importance of proper data handling and statistical power without extensive cleaning.
