Counting Sheep PSG

EEGLAB-compatible manual sleep stage scoring, signal processing and event marking of polysomnographic (PSG) data for MATLAB.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes.

Prerequisites

Mac, PC and Linux compatible.
Designed for use with EEGLAB 2023 or later (https://eeglab.org) on Matlab R2020b or later (R2022b or later recommended).
For use on continuous EEGLAB datasets (*.set).

Works best if recording includes (in the EEG.event structure):

• Recording start time event (at first data point).
• Lights Off and Lights On events.

Installing

Simply unzip 'countingSheepPSG' and add to Matlab path.
Alternatively, unzip and move folder to '~/eeglab/plugins/' directory for EEGLAB GUI integration.

Usage

1. Launch by typing 'countingSheepPSG' at command prompt.
2. Customize display montage in: ~/montages/sleep_montage_default.m (rename and save to new file)
3. Loads an EEGlab PSG dataset for signal preprocessing and annnotation.

Supported Data Formats:

• EEGLAB Datasets (default)
• European Data Format (EDF)
• Brain Products Format (VHDR)

Sleep Scoring Keyboard Shortcuts:

• 0 - Wake
• 1 - NREM 1
• 2 - NREM 2
• 3 - SWS
• 4 - REM
• . - Unscored
• backspace/delete - delete seelcted event(s)

Event Marking Mode:

• Single-point events can be created using single mouse click
• Events with a duration can be created using mouse click-and-drag
• Enable 'all channels' mode to mark events without a channel
• Single-click existing event to select/deselect for delete/merge

Signal processing (using built-in EEGlab functions)

• interpolate bad channels
• downsampling
• filtering
• re-referencing (beta)
• channel edit (beta)
• Independent component analysis (ICA)
• Artifact Subspace Reconstruction (ASR)
• Power spectral analysis - FTT (beta)

Automatic Event Detection:

• Automatic movement artifact detection
• Automatic spindle detection (using EEGlab 'detect_spindles' plugin)
• Automatic slow wave detection (using EEGlab 'PAA' plugin)
• Spindle-slow wave coupling analysis (coming soon...)
• Automatic rapid eye movement detection (coming soon...)
