Data Sheet 1_Cerebral blood flow and functional connectivity immediate changes following i

Twenty patients with major depressive disorder and twenty matched healthy controls underwent resting-state MRI scans to assess the immediate effects of intradermal acupuncture. The study, authored by Zelin Yu and last updated in April 2026, provides neuroimaging data on changes in cerebral blood flow and functional connectivity strength across brain regions like the precuneus and superior frontal gyrus. Results indicate acupuncture induced significant alterations in neurovascular coupling, suggesting enhanced coordination between perfusion and network integration.

Use Cases

• Analyze immediate neurovascular coupling changes based on pre- and post-acupuncture MRI scans mentioned in the description
• Compare cerebral blood flow and functional connectivity patterns between patients with major depressive disorder and healthy controls
• Investigate regional brain activity in sensorimotor and cognitive control areas like the precuneus and superior temporal pole
• Study the relationship between cerebral perfusion and functional network integration as measured by the CBF/FCS ratio

Strengths

• Includes data from 20 patients with major depressive disorder and 20 matched healthy controls, providing a comparative baseline
• Analyzes multiple neuroimaging metrics: cerebral blood flow, functional connectivity strength, and their coupling ratio
• Data is shared under a permissive CC-BY-4.0 license, allowing for broad reuse and adaptation

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download
• The dataset is relatively small at 7.9 MB, which may limit statistical power for some analyses
• Data is stored in a DOCX file format, which is atypical for structured neuroimaging data and may require format conversion
