fMRI Brain Activation Data Following 60 Hz Magnetic Field Exposure

Dryad hosts data from a study on human brain activation changes after exposure to a 60 Hz, 3000 µT magnetic field. The dataset includes fMRI measurements from two cohorts performing motor and cognitive tasks, with pilot results from 9 subjects and a full study involving 20 subjects for a finger-tapping task and 21 for a mental rotation task. The research, authored by Alexandre Legros, was published in 2020.

Use Cases

• Analyze fMRI activation patterns from the finger-tapping task to identify brain regions modulated by the 3000 µT MF exposure.
• Compare pre- and post-exposure fMRI data from the mental rotation task to study residual effects on cognitive processing.
• Correlate task performance metrics with fMRI activation changes to investigate the dissociation between brain activity and behavioral outcomes.

Strengths

• Data originates from a controlled fMRI study with specific exposure parameters: 60 Hz, 3000 µT for one hour.
• Includes results from two distinct cohorts: 20 subjects for a motor task and 21 subjects for a cognitive task.
• Pilot study with 9 subjects demonstrates technical feasibility for detecting subtle brain activation changes.

Limitations

• Sample sizes are modest (cohorts of 20 and 21), limiting statistical power for subgroup analyses.
• The dataset's scope is specific to a single exposure frequency and intensity, limiting generalizability to other ELF-MF conditions.
• Data collection methodology and specific variables (e.g., fMRI time series, region-of-interest metrics) are not detailed in the provided description.
