EPFL PlasMA: Behavioral and fMRI Data from Transcranial Stimulation Experiments

EPFL researchers collected behavioral logs and functional MRI scans from young and elderly participants undergoing transcranial temporal interference stimulation (tTIS). The dataset includes raw key press logs, sequence performance summaries, and processed neuroimaging contrasts. Data organization suggests experiments involved multiple stimulation conditions and independent component analysis for rs-fMRI.

Use Cases

• Analyzing the impact of stimulation conditions on behavioral sequence performance based on the provided randomization and log files.
• Investigating age-related differences in brain network activity using the provided rs-fMRI and task-based fMRI data.
• Training models to predict behavioral outcomes from neuroimaging features based on the processed contrast data.
• Replicating the independent component selection process for resting-state fMRI analysis mentioned in the description.

Strengths

• Includes data from two distinct participant groups (young and elderly), allowing for comparative analysis.
• Contains both raw behavioral logs and processed neuroimaging outputs, offering multiple analysis entry points.
• Anatomical MRI images were defaced for privacy, indicating some data anonymization steps were taken.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Row count and dataset scale are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
