Brain Connectivity and THC Analgesia in Chronic Neuropathic Pain

Data from a study of 15 patients with chronic radicular neuropathic pain, analyzing functional brain connectivity changes after THC administration. The dataset includes pain assessments and resting-state fMRI scans from a randomized, double-blind, placebo-controlled trial. It examines connectivity between the anterior cingulate cortex (ACC), sensorimotor cortex, and dorsolateral prefrontal cortex (DLPFC).

Use Cases

• Analyze correlations between THC-induced pain reduction and changes in functional connectivity between the ACC and sensorimotor cortex.
• Use graph theory measures on brain network dynamics to identify local connectivity reductions in pain-processing areas like the DLPFC.
• Investigate baseline functional connectivity between the ACC and sensorimotor cortex as a potential predictor for individual THC analgesic response.

Strengths

• Data originates from a randomized, double-blind, placebo-controlled trial with a counterbalanced, within-subjects design.
• Includes functional resting-state brain scans and pain assessments from 15 patient participants.
• Focuses on specific, well-defined brain regions (ACC, sensorimotor cortex, DLPFC) and their connectivity related to pain modulation.

Limitations

• Small sample size of 15 patients limits statistical power and generalizability of findings.
• Study population is specific to chronic radicular neuropathic pain, which may not represent other pain conditions.
• Dataset scope is confined to a single experimental intervention (sublingual THC) without longitudinal follow-up data.
