Four-Hour Electrogastrography Recordings from Six Healthy Adults

Four-channel electrogastrography recordings from six adult participants during a four-hour protocol. The data captures gastric electrical activity across fasting, food intake, and postprandial periods. The dataset was authored by Alonso Ochoa and last updated in June 2026.

Use Cases

• Characterizing gastric rhythm behavior based on the described fasting and postprandial stages.
• Estimating dominant frequency of gastric activity using the raw multichannel EGG signals.
• Performing spectrogram-based evaluation of gastric electrical activity over time.
• Comparing pre- and post-meal gastric activity based on the structured experimental protocol.

Strengths

• Includes raw four-channel EGG signals from a four-hour recording session per participant.
• Covers three distinct experimental stages: fasting, food intake, and postprandial periods.
• Provides basic participant data including age, height, weight, BMI, and anatomical reference measurements.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
• Data is from a small cohort of six participants, which may limit generalizability.
