How anesthetics and pain medicines change the human brain

Neuroimaging to identify the neural correlates of anesthetic and analgesic action in humans

NIH-funded research University of Pittsburgh at Pittsburgh · NIH-11170429

Adults will have brain scans and monitoring while given common anesthetics and pain medicines to learn how these drugs block pain and memory during painful moments.

What this research studies

You would come to the University of Pittsburgh for sessions in a high-strength MRI scanner. During each visit you'll receive steady doses of one of several commonly used anesthetics while doing simple cognitive tasks and receiving brief, carefully controlled painful stimuli. While this happens we will record your brain activity with high-field fMRI along with EEG, skin conductance, and heart rate to capture how the drugs change brain signals and behavior. The team will compare responses across multiple drug classes to find where and how anesthetics and analgesics block memory formation, conditioned fear responses, and pain perception.

Who could benefit from this research

Good fit: Healthy adults aged 21 or older who can safely undergo MRI and brief anesthetic exposure and who are willing to receive controlled short pain stimuli would be ideal candidates.

Not a fit: People who are under 21, pregnant, have implanted metal devices, unstable medical conditions, or who need treatment for ongoing chronic pain are unlikely to be eligible or directly benefit from participating.

Why it matters

Potential benefit: Results could help doctors make anesthesia and pain control safer and better targeted to prevent pain and traumatic memories.

How similar studies have performed: Prior neuroimaging and anesthesia research has provided important clues, but combining high-field fMRI, EEG, autonomic measures, and multiple drug classes in the same protocol is relatively novel.
