Motor Evoked Potential Measurements During Action Observation

Figshare dataset by Aynur Ragimova contains electrophysiological measurements from a transcranial magnetic stimulation study. It investigates the relationship between cortical excitability-inhibition balance and muscle-specific motor resonance during action observation. The data is provided in a 122.0 KB XLSX file.

Use Cases

• Analyze correlations between pre-AO SICI measures and task-related MEP modulation in the ADM muscle.
• Model the relationship between post-AO ICF values and MEP responses during observation of specific finger movements.
• Compare corticospinal excitability indices (SP, ICF, SICI) before and after the action observation task.
• Examine muscle-specific MEP responses (FDI vs. ADM) during observation of index versus little finger movements.

Strengths

• Data originates from a controlled neurophysiological study using single-pulse Transcranial Magnetic Stimulation (spTMS).
• Includes multiple corticospinal excitability protocols: single-pulse (SP), intracortical facilitation (ICF), and short-interval intracortical inhibition (SICI).
• Measures motor evoked potentials (MEPs) from two distinct hand muscles (FDI and ADM) during specific action observation conditions.

Limitations

• The dataset is very small at 122.0 KB, indicating limited scope and likely a low number of participant records.
• Specific sample size (rows) and measured variables (columns) are not provided, complicating reproducibility and meta-analysis.
• Data is focused on a specific experimental paradigm, limiting generalizability to other motor resonance contexts.
