Functional Near-Infrared Spectroscopy Data for Human Body Malodor Evaluation

Eighteen healthy Japanese adults in their 40s participated in a study measuring brain activity via functional near-infrared spectroscopy (fNIRS) during exposure to three odor stimuli. The dataset likely contains physiological and neural response data, supporting objective evaluation of human body malodor. The data was authored by Yoshihiro Inoue and is available under a CC-BY-4.0 license.

Use Cases

• Analyze neural correlates of odor perception based on oxygenated hemoglobin concentration changes in cortical regions.
• Compare physiological stress responses to different odors based on heart rate, nose-tip temperature, fingertip blood flow, and salivary markers.
• Investigate relationships between subjective perceptual ratings and objective neural measurements.
• Develop models for objective odor evaluation in sensory science applications.

Strengths

• Includes data from 18 participants with balanced gender representation (9 women, 9 men).
• Combines neural (fNIRS), physiological (heart rate, temperature), and endocrine (salivary cortisol, alpha amylase) measurements.
• Odor stimuli were adjusted for intensity to allow continuous inhalation without marked mood changes.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small (746.5 KB), indicating limited scope.
