A Fractal Model for Redefining EEG Frequency Bands

A theoretical study proposes a geometric framework for redefining electroencephalographic (EEG) frequency bands based on logarithmic scaling. The framework uses the mean adult alpha rhythm as a reference and a constant scaling ratio of 1.7275 to derive band centers and boundaries. The model was authored by Sultan Tarlacı and published on figshare in March 2026.

Use Cases

• Developing new EEG analysis pipelines based on the proposed non-overlapping, proportional band structure.
• Testing hypotheses about oscillatory brain structure using the model's explicit generative rule for discrete band centers.
• Comparing conventional EEG band definitions with the model's geometrically derived subdivisions within alpha and gamma ranges.

Strengths

• Provides an explicit generative rule for discrete EEG band centers and transition frequencies.
• The model-derived theta-alpha transition (~7.98 Hz) is noted for its proximity to the Earth's Schumann resonance (~7.83 Hz).

Limitations

• The dataset is a theoretical study document (759.3 KB DOCX file) and does not contain empirical EEG data.
• Row count and column-level documentation are absent; the content is purely conceptual.
• Freshness should be verified; the last update date is March 2026.
