Dataset Description

Overview

This dataset contains EEG recordings from a study investigating neural activity changes before and after an intervention. The data are organized following the Brain Imaging Data Structure (BIDS) specification.

The dataset includes multiple participant groups and timepoints:

• Group 1, Group 2, Group 3
• Pre-intervention (pre) and Post-intervention (post)

Participants

Participants are labeled using anonymized IDs (e.g., sub-001, sub-002, etc.). Demographic and session-related information are provided in the corresponding TSV files where applicable.

Data Structure

The dataset follows the BIDS format:

• sub-XXX/
  • ses-pre/ or ses-post/
    • eeg/
      • EEG recordings (.edf)
      • Metadata files (.json)
      • Events files (.tsv)

Each subject contains EEG recordings organized by session (pre/post).

Experimental Design

The study compares neural activity before and after an intervention. Participants are divided into different groups to evaluate potential differences in outcomes.

Data Acquisition

EEG data were recorded using standard acquisition systems. Detailed acquisition parameters are stored in the accompanying JSON sidecar files.

Data Processing

The dataset has been reorganized into BIDS format. File naming, metadata, and structure have been standardized to ensure compatibility with BIDS-compliant tools.

Known Issues

• Some warnings may appear during BIDS validation but do not affect data usability.
• All critical validation errors have been resolved.

Usage Notes

This dataset can be used for:

• EEG signal analysis
• Functional connectivity studies
• Pre/post intervention comparisons
