La neuro-imagerie fonctionnelle, avec l’IRM fonctionnelle (IRMf) et la Tomographie par Emission de Positons (TEP), a permis de grandes avancees dans la comprehension des mecanismes physiopathologiques de la migraine et de l’algie vasculaire de la face (AVF). La premiere etude en TEP lors de crises de migraine sans aura a permis de mettre en evidence une activation du tronc cerebral persistant apres soulagement de la douleur par le sumatriptan [1]. Depuis cette donnee a ete confirmee dans la… 


A positron emission tomographic study in spontaneous migraine.
The findings provide clear evidence of dorsal pontine activation in migraine and reinforce the view that migraine is a subcortical disorder modulating afferent neural traffic.
Posterior Cerebral Hypoperfusion in Migraine Without Aura
Significant relative bilateral posterior cortical hypoperfusion was found and persisted after headache relief following sumatriptan injection within 4 h after the attack onset, suggesting a common pathogenesis in migraine with and without aura.
Functional MRI-BOLD of brainstem structures during visually triggered migraine
Activation (hyperoxia and blood volume increase) of the red nucleus and substantia nigra in association with visually triggered symptoms of migraine suggest that these brainstem structures are a part of a neuronal network activated during an attack.
Correlation between structural and functional changes in brain in an idiopathic headache syndrome
The results indicate that the current view of the neurobiology of cluster headache requires complete revision and that this periodic headache is associated with a hitherto unrecognized brain abnormality in the hypothalamic region.
Mechanisms of migraine aura revealed by functional MRI in human visual cortex
High-field functional MRI with near-continuous recording during visual aura in three subjects observed blood oxygenation level-dependent signal changes that strongly suggest that an electrophysiological event such as CSD generates the aura in human visual cortex.
Brief report: bilateral spreading cerebral hypoperfusion during spontaneous migraine headache.
A series of patients who had migraine headaches during serial cerebral blood-flow measurement by the intracarotid xenon-133 technique observed a pattern of localized decreases in flow that appeared to spread contiguously along the cerebral cortex.
PET and MRA findings in cluster headache and MRA in experimental pain
Dilatation of cranial vessels is not specific to any particular headache syndrome but generic to cranial neurovascular activation, probably mediated by the trigeminoparasympathetic reflex.
Brain stem activation in spontaneous human migraine attacks
Findings support the idea that the pathogenesis of migraine is related to an imbalance in activity between brain stem nuclei regulating antinociception and vascular control.
Hypothalamic stimulation for intractable cluster headache: Long-term experience
Hypothalamic stimulation is an effective, safe, and well-tolerated alternative to surgery for chronic patients with drug-refractory CH.
Stereotactic stimulation of posterior hypothalamic gray matter in a patient with intractable cluster headache.
To the Editor: Cluster headache is the most severe form of primary headache.1 Positron-emission tomography has shown activation of the homolateral posterior inferior hypothalamic gray matter during...
