Supplementary Material for a tACS Clinical Trial on Chronic Insomnia

A figshare admin karger uploaded supplementary material on April 18, 2026. The 7.9 MB DOCX file contains data from a 4-week, double-blind, randomized, sham-controlled trial investigating high-intensity transcranial alternating current stimulation (tACS) on 18 patients with chronic insomnia. The material includes longitudinal resting-state fMRI data, clinical results, and analyses of brain network activity.

Use Cases

• Analyze changes in Default and Salience/Ventral Attention network activity based on fMRI data mentioned in the description
• Correlate clinical sleep score improvements with reductions in spontaneous brain activity based on PSQI scores
• Study topological reorganization of brain networks based on graph theoretical analysis metrics
• Compare active versus sham treatment effects on functional connectivity within specified networks

Strengths

• Data originates from a 4-week, double-blind, randomized, sham-controlled clinical trial
• Includes longitudinal resting-state fMRI data from 18 patients who completed the protocol
• Clinical results show significant PSQI score reduction (13.8 vs. 7.7) in the active tACS group

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• The 7.9 MB size suggests a small dataset, potentially limiting analysis scope
