Pathology and Pathophysiological Mechanisms of Migraine Aura

This scections starts contrasting the different theories about the origin of the aura. It follows a detailed documentation of computer models that help to understand this complex phenomenon.

Neural vs Vascular Theory of Migraine Aura

Whether migraine aura has a neural or vascular cause is a current dispute in the literature of migraine pathology. [more]

Modelling Migraine Aura

Neural networks and nonlinear dynamics can help to explain what happens to the brain during an migarine with aura. It is hoped that this computational neuroscience approach provides a new route to migraine etiology. [more]
