Modelling Migraine Aura

Beginning with the pioneering study of Lashley from 1941, notions about functional models have unfolded in a number of scientific papers covering a period up to the present.

Lashley's scotomas can be mapped from the visual field (left) onto the cortical surface (right). The kidney shape is transformed to a wave front with constant width (Dahlem, 2000). © 2000 Markus Dahlem

Model of Karl Lashley (1941)

A first attempt to connect migraine with a cerebral propagation phenomenon was already made in 1941 by Lashley. He layed the ground for many follow up theoretical research. [more]

Model of Norbert Wiener and Arturo Rosenblueth (1946)

Norbert Wiener and Arturo Rosenblueth gave the starting signal for theoretical research in this field. [more]

Model of Whitman Richards (1971)

Richards looked for details in visual aura pattern to deduce functional cortical organisation. [more]

Model of Eric Schwartz (1980)

Schwartz argued on the basis of detailed cortical circuitry to explain visual aura pattern. [more]

Model of Otto-Joachim Grüsser (1995)

Quantitative observations on the shape and position of visual migraine aura were provided by this renowned researcher. [more]

Model of James A. Reggia (1996)

The neurocomputational perspective was further developed by a detailed neural network model. [more]

Model of Markus Dahlem (2000)

Dahlem developes neural network models of the visual cortex to test whether the aura can be understood in terms of functional cortical organization and to reveal the underlying cause. [more]
