Summer Webinar - Power Spectral Analysis and Rhythmic vs. Arrhythmic Components

The Quebec Sleep Research Network is pleased to offer five summer webinars on analyzing sleep data using the Snooz toolbox. These webinars will be conducted in English only, but the Q&A sessions will be bilingual.

Title of Snooz Summer Webinar #3 : Power Spectral Analysis and Rhythmic vs. Arrhythmic Components

Presenter : Jean-Marc Lina, PhD, et Mohammad Hasan, MASc

Where : Online

When : June 2, 2026, from 10 a.m. to 11:30 a.m.

Learning objectives for Snooz Summer Webinar #3 :

1. Explain the principles of power spectral analysis and distinguish between rhythmic (oscillatory) and arrhythmic (aperiodic/1/f) components of EEG signals across sleep and altered states ;
2. Use Snooz tools to compute and parameterize spectral features (e.g., band power, spectral exponent, oscillatory peaks) and interpret their physiological relevance ;
3. Critically evaluate methodological choices in spectral analysis and understand how analytic parameters influence scientific conclusions.

General learning objectives of the Snooz Summer Webinars :

1. Describe the architecture and scope of the Snooz platform, including how its modules support large-scale, reproducible sleep and EEG research ;
2. Apply Snooz tools to preprocess, analyze, and visualize sleep and neurophysiological data, using standardized and reproducible pipelines ;
3. Select appropriate analytic approaches for specific scientific questions in sleep and consciousness research ;
4. Critically evaluate the assumptions, strengths, and limitations of different analysis methods implemented in Snooz ;
5. Design scalable and transparent analysis workflows that facilitate collaboration, data sharing, and extension to new datasets or modalities.
