Matlab Scripts for EEG Sleep Architecture Analysis

Analysis files from a neuroscience study on brain state regulation include Matlab scripts for processing EEG data and a Prism file for statistical analysis. The scripts handle tasks like resampling EEG signals to 256 Hz, calculating spectral power density, and identifying sleep episodes and brief awakenings. Author Elise Meijer published these resources under a CC BY 4.0 license in March 2026.

Use Cases

• Resample raw EEG signals to a standard 256 Hz sampling rate using the provided TDTSDK Matlab package.
• Calculate EEG spectral power density per epoch with the PWelch function, applying optional notch filters.
• Identify uninterrupted episodes of NREM sleep, REM sleep, and wakefulness using preset duration variables.
• Detect brief awakenings within sleep episodes based on configurable interruption thresholds.
• Perform statistical analysis of sleep architecture parameters using the included Prism file.

Strengths

• Includes specific Matlab functions for key EEG analysis steps like resampling and spectral power calculation.
• Scripts are configured with preset variables for episode detection, providing a structured analytical approach.
• Resources are published under a permissive CC BY 4.0 license, facilitating reuse.

Limitations

• The dataset is very small at 401.6 KB, containing only analysis scripts and one statistical file, not raw EEG data.
• No sample data or column information is provided, limiting understanding of the input data structure.
• Utility is dependent on proprietary software (Matlab, Prism) and specific toolboxes (TDTSDK).
