EEG Dataset Capturing Brain Responses of Nutrition in children aged 8–11 years

This dataset comprises 50 quantitative Electroencephalogram (qEEG) reports derived from pediatric subjects aged 8 to 10 years. The recordings provide a comprehensive neurophysiological profile, including spectral power analysis and topographical brain mapping, organized into four primary folders based on the elementary school (SD) location of the subjects. Data Structure and Institutional Categorization The dataset is categorized into folders corresponding to the following educational institutions: 1. SD Muhammadiyah Karangkajen: Includes 10 subjects (IDs 21, 22, 23, 24, 27, 29, 30, 31, 32, 33). Data in this group typically exhibit Delta and Theta wave dominance, with a recorded peak power of 31.0 μV² at location P3-A1 for subject ID 23. 2. SD Muhammadiyah Argosari: Includes 15 subjects (IDs 4, 5, 6, 7, 8, 9, 10, 11, 44, 45, 46, 47, 48, 49, 50). This cohort contains extreme Delta power values, notably in ID 45 (1900.4 μV²) and ID 46 (1900.2 μV²). 3. SD Muhammadiyah Kaputran: Includes 15 subjects (IDs 12, 13, 14, 15, 16, 17, 18, 19, 51, 53, 54, 55, 56, 57, and 21). Significant Alpha 2 activity was identified in this group, with subjects ID 56 and ID 54 reaching peak powers of 1942.7 μV². 4. SD Menteng: Contains 17 subjects not included in the previous categories (IDs 20, 25, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75). Dominant activity is primarily in the Delta (0.8–3.8 Hz) band, with exceptional peak power values recorded for subject ID 72 (3406.1 μV²) and subject ID 75 (1031.6 μV²). Technical Recording Specifications All qEEG data were recorded using standardized clinical parameters to ensure technical consistency: - Recording Speed: 30 mm/s. - Sensitivity: 5.0 mm / 50 µV. - Montage: Monopolar configuration with 16 primary channels (Fp1, Fp2, F3, F4, C3, C4, P3, P4, O1, O2, F7, F8, T3, T4, T5, T6) referenced to the auricles (A1, A2). - Physiological Context: Simultaneous 2-channel Electrocardiogram (ECG1, ECG2) recordings. Clinical Frequency Band Analysis Spectral power is analyzed across six defined clinical frequency ranges: - Delta: 0.8–3.8 Hz. - Theta: 4.0–7.8 Hz. - Alpha 1 & 2: 8.0–12.8 Hz. - Beta 1 & 2: 13.0–30.0 Hz. Visualization Formats Each subject report includes multiple analytical visualizations: - Brain Electrical Activity Mapping (BEAM): Includes Numerical BEAM (µV² values), Side View projections, and Three-Dimensional Rotary BEAM. - Spectral Graphs: Power Spectrum Graphs (5Hz scale), Compressed Spectrum Graphs (temporal), and Spectrum Rectangle Graphs (power distribution). This dataset is intended for advanced research in neurophysiology, pediatric neuroscience, and biomedical signal processing.
