2021-04-14 · Gray matter heterotopia is a neurological disorder that is characterized by the gray matter in the brain being located in the wrong part of the brain. It is associated with epilepsy and can affect higher brain functions and motor skills. Seizures are generally resistant to medication. Common symptoms reported by people with gray matter heterotopia
(Heterotopia means "out of place.") Normally, the neurons that make up the outer surface of the brain (cerebral cortex) are distributed in a well-organized and multi-layered way. In people with subcortical band heterotopia, some neurons that should be part of the cerebral cortex do not reach it.

From a clinical perspective, affected patients are best divided into three groups: subependymal, subcortical, and band heterotopia (also called double cortex). CAUTION patients with heterotopia, who have earlier age of seizure onset, may have a change in their seizure types over time, with the emergence of epileptic spasms or generalized seizure types, such as atypical absence, atonic and tonic seizures. Developmental and cognitive impairments are more common in this group. Periventricular nodular heterotopia is a malformation of cortical development due to impaired neuronal migration.
Here, we report a patient presenting with epilepsy as new feature in CEP135 related disease and provide the first brain-MRI images identifying subcortical heterotopia as underlying cere-bral malformation.
The brain of the tish rat displays bilateral subcortical heterotopia reminiscent of those found in double cortex. The heterotopia consists of misplaced cortical neurons and glia that retain several basic features of normal neocortex, including topographic connectivity with subcortical targets.
Heterotopia within the brain is often divided into three groups: subependymal heterotopia, focal cortical heterotopia and band heterotopia. Another example is a Meckel's diverticulum , which may contain heterotopic gastric or pancreatic tissue. Disruption of these steps yields different types of cortical malformations including gray matter heterotopia, characterized by the ectopic position of neurons along the ventricular walls or in the deep white matter. Heterotopias can occur within the subependymal and periventricular (neural stem cell) zone just overlying the ventricles of the brain, and subcortically just beneath the cortical gray matter.

av M Simonsson · 2014 · Citerat av 11 — Michel Foucault developed the concept of heterotopia in his “Of Other Spaces” Irish artist Brian O'Doherty in his essays compiled in Inside the White Cube.
Periventricular nodular heterotopia is a disorder of neuronal migration in which neurons fail to migrate appropriately from the ventricular zone to the cortex during development, resulting in the formation of nodular brain tissue lining the ventricles. Detection of heterotopia generally occurs when a patient receives brain imaging -- usually an MRI or CAT scan -- to diagnosis seizures that are resistant to medication. Correct diagnosis requires a high degree of radiological skill, due to the heterotopia's resemblance to other masses in the brain.

More recently, it has come to be recognized that focal heterotopias may also show a range of psychiatric problems, including cognitive and behavioral impairments. However, because focal heterotopias are Heterotopia means "out of place." In normal brain development, neurons form in the periventricular region, located around fluid-filled cavities (ventricles) near the center of the brain. The neurons then migrate outward to form the exterior of the brain (cerebral cortex) in six onion-like layers. 2014-01-26 · Heterotopias can occur within the subependymal and periventricular (neural stem cell) zone just overlying the ventricles of the brain, and subcortically just beneath the cortical gray matter. The image below is a hemisphere of a normal adult brain to help you visualize where the different heterotopias may occur. We examined brain tissue from four children with subcortical or periventricular nodular heterotopia of different aetiologies: one with severe epilepsy following focal brain trauma at 17 weeks gestation, one with hemimegalencephaly and intractable epilepsy, one with focal cortical dysplasia and intractable epilepsy, and one dysmorphic term infant with associated hydrocephalus and polymicrogyria.
