MIGRAINE PATHOPHYSIOLOGY

Description

As a mean to advance mechanistic understanding of migraine, the research activity focuses on the investigation of the cellular and circuit mechanisms of the primary brain dysfunctions that cause a rare monogenic form of migraine with aura (familial hemiplegic migraine, FHM), using FHM mouse models. These animal models include knock-in mice carrying FHM type 1 and type 2 mutations in the genes encoding the neuronal voltage-gated calcium channel CaV2.1 and the astrocytic alpha2 Na/K ATPase, respectively.

The experimental approach is to combine experiments in acute cortical slices and in head-fixed awake animals using electrophysiological, imaging and optogenetic techniques to study the brain pathogenic alterations at a multi-scale level (cellular, synaptic, local microcircuit and mesoscale circuit levels).
