Table 1_Effects of heat-treated Lactobacillus gasseri CP2305 on brain oscillatory activity

28 healthy adults aged 20–44 participated in a double-blind, randomized, crossover, placebo-controlled trial. The dataset likely contains results from electroencephalography (EEG), heart rate variability, and psychological assessments (VAS, POMS2) measuring the effects of a postbiotic on mental stress and brain alpha power. The dataset was uploaded by Reiko Tanihiro to figshare in 2026 under a CC-BY-4.0 license.

Use Cases

• Analyze the relationship between postbiotic consumption and changes in brain alpha oscillatory activity based on EEG data.
• Model the correlation between parasympathetic nervous system activity (via RMSSD) and subjective stress scores (VAS, POMS2).
• Investigate potential mediating effects suggested by in vitro serotonin (5-HT) secretion data from enterochromaffin cells.

Strengths

• Data originates from a double-blind, randomized, crossover, placebo-controlled clinical trial, a rigorous study design.
• Includes multimodal measurements: physiological (EEG, HRV), psychological (POMS2, VAS), and in vitro (serotonin assay).
• Clinical trial is registered with a public identifier (UMIN000056164), supporting transparency.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is small (677.5 KB), indicating limited scope, likely containing summary results rather than raw time-series data.
