Motor Resonance and Cortical Excitability Measurements from TMS Study

Figshare hosts a neurophysiological dataset from a study investigating GABAergic and glutamatergic mechanisms of cortical excitability during action observation. The data includes motor evoked potential (MEP) measurements from the first dorsal interosseous (FDI) and abductor digiti minimi (ADM) muscles, collected using single-pulse, intracortical facilitation (ICF), and short-interval intracortical inhibition (SICI) transcranial magnetic stimulation protocols. The dataset, provided in XLSX format, is associated with research by Aynur Ragimova.

Use Cases

• Analyze correlations between pre- and post-action observation ICF and SICI measurements and task-related MEP modulation.
• Compare SP-induced MEP amplitudes in the FDI and ADM muscles across different observed finger movement conditions.
• Investigate individual differences in motor resonance by modeling the relationship between stable excitatory-inhibitory properties indexed by ICF and SICI.
• Examine changes in corticospinal excitability indices before and after action observation for the SP, ICF, and SICI protocols.

Strengths

• Data is directly linked to a specific, peer-reviewed neuroscience study with a clear methodological description.
• Includes measurements from two distinct hand muscles (FDI and ADM) under multiple TMS protocols (SP, ICF, SICI).
• Released under the permissive CC BY 4.0 license, facilitating open reuse and analysis.

Limitations

• The dataset is very small at 11.8 KB, indicating limited scope and likely a low number of participant observations.
• Sample data and column definitions are unavailable, complicating initial data exploration and requiring careful interpretation of the accompanying manuscript.
• As a single-study dataset, its generalizability to broader populations or different experimental conditions is inherently limited.
