Motor Evoked Potentials from TMS During Action Observation

A 2026 study by Aynur Ragimova provides tabular data on motor evoked potentials (MEPs) measured via transcranial magnetic stimulation (TMS) during an action observation task. The dataset includes measurements from the first dorsal interosseous (FDI) and abductor digiti minimi (ADM) muscles under different TMS protocols. It captures individual differences in corticospinal excitability linked to glutamatergic and GABAergic mechanisms.

Use Cases

• Analyze correlations between pre- and post-action observation ICF/SICI excitability measures and task-related MEP modulation in FDI and ADM muscles.
• Model the relationship between GABA-A mediated inhibition (SICI) and the suppression of SP-induced ADM MEPs during index finger movement observation.
• Investigate how glutamatergic facilitation (ICF) in the FDI muscle correlates with SP-induced FDI MEP responses during observation of index finger movements.
• Compare corticospinal excitability changes in the FDI and ADM muscles across single-pulse (SP), ICF, and SICI TMS protocols before and after action observation.

Strengths

• Data originates from a peer-reviewed neuroscience study investigating cortical excitability mechanisms.
• Includes physiological measurements from two distinct hand muscles (FDI and ADM) under multiple TMS protocols.
• Dataset is openly available under a CC BY 4.0 license for reuse and analysis.

Limitations

• The dataset is small in scale at 975.1 KB, indicating limited sample size or number of observations.
• Specific row and column counts are unknown, making it difficult to assess the dataset's analytical scope.
• Data is confined to a specific laboratory TMS experiment, limiting generalizability to broader populations or conditions.
