Functional activation of microgyric visual cortex in a human

Ann Neurol. 2001 Nov;50(5):672-6. doi: 10.1002/ana.1262.

Abstract

We report on the case of a 20-year-old man with bilateral parasagittal parieto-occipital polymicrogyria and epilepsy. Functional magnetic resonance imaging responses to reversing checkerboard and interhemispheric electroencephalogram coherence changes to moving gratings were investigated. Results of both studies indicate that the polymicrogyric cortex was activated by visual stimuli, suggesting preserved function in the dysplastic area.
