Brain circuits behind migraine pain
Brain Circuits of Migraine Pain
Researchers are mapping the brain pathways that drive migraine pain to better understand why some treatments don't stop attacks.

What this research studies
This project aims to map the brain pathways that carry migraine pain signals and identify key nodes such as the parabrachial nucleus and central amygdala. Researchers combine preclinical lab work — including activating dural afferents, neuronal tracing, pharmacology, and optogenetics in animal models — with human neuroimaging findings to link peripheral signals to central pain circuits. The team will study reasons why some people do not respond to CGRP-targeting drugs and search for non‑CGRP peripheral or central mechanisms that cause migraines. The findings are intended to guide new targets for therapies that could help patients with difficult-to-treat migraine.
Who could benefit from this research
Good fit: People with frequent, severe, or treatment-resistant migraine would be the most likely future candidates to benefit from therapies informed by this work.
Not a fit: People whose migraines are well controlled on existing medications or who have non-migraine headache disorders are less likely to receive direct benefit from this project.
Why it matters
Potential benefit: If successful, this work could point to new treatment targets for people whose migraines do not respond to current CGRP-based therapies.
How similar studies have performed: CGRP-blocking medications have helped many patients, while circuit-level mapping has shown promising results in animal studies but has limited direct clinical evidence so far.
