Area of Science:

• Neuroscience
• Biomedical Engineering
• Gerontology

Background:

• Daily activity analysis in older adults requires accessible electroencephalogram (EEG) tools.
• Current barriers limit access to EEG technology for a wider research community.
• Development of user-friendly, free EEG analysis software is crucial.

Purpose of the Study:

• To introduce a newly developed, free tool set for electroencephalogram (EEG) analysis.
• To facilitate daily activity analysis in older adults.
• To lower the entry barrier for new researchers in EEG analysis.

Main Methods:

• The tool set was developed using the Perl programming language.
• It enables import, averaging, waveform display, and iso-potential scalp topography.
• Scripts are easily editable, ensuring transparency and flexibility.

Main Results:

• Basic EEG processing functions, including averaging, waveform display, and scalp topography, have been implemented.
• Validation was performed by comparing results with commercial software.
• The system provides free, editable scripts without "black boxes".

Conclusions:

• The developed tool set offers an easy-to-start, flexible, and modifiable platform for EEG analysis.
• It is expected to attract and support new researchers in the field of EEG.
• This initiative aims to broaden participation in EEG research, particularly for older adult activity analysis.
