Subcortical band heterotopia (SBH) or 'double cortex', is a congenital brain abnormality that results from aberrant migration of neurons during development of the cortex. MRI shows a continuous band of heterotopic grey matter located between the cortex and ventricular walls, separated from them by a thin layer of white matter. The condition is quite rare, found predominantly in females, and is occasionally familial with an X-linked dominant inheritance. Current research has focused on genetic and neurological correlates, with cognitive assessment restricted to a global measure of general intellectual functioning.
