Migraine Patient ERP Data: P50 and CNV Components for Cortical Habituation Study

A study by Jing Li, uploaded to figshare in April 2026, systematically evaluates electrophysiological alterations in migraine patients. The 674.6 KB document likely contains tabular data on event-related potential (ERP) components P50 and Correlated Negative Variation (CNV), measuring latencies, amplitudes, suppression rates, and spectral energy. Findings indicate impaired sensory gating and cognitive anticipation functions in patients.

Use Cases

• Classifying migraine patients based on P50 latency and suppression rate features.
• Modeling cortical excitability using CNV amplitude and area values.
• Analyzing spectral power changes in theta and alpha bands across brain regions.
• Investigating correlations between early sensory gating (P50) and late cognitive anticipation (CNV) metrics.

Strengths

• Study systematically evaluates both early sensory gating (P50) and late cognitive anticipation (CNV) functions.
• Provides an objective, quantitative neurobiological marker profile for migraine.
• Data is shared under a permissive CC-BY-4.0 license.

Limitations

• Row count and column-level documentation are unknown, limiting suitability assessment.
• The dataset is small at 674.6 KB, indicating a limited scope or sample size.
• The primary data format is a DOCX file, which may require extraction of structured data.
