What is heterotopic grey matter?

What is heterotopic grey matter?

OVERVIEW. Grey matter heterotopia is a malformation of cortical development, where cortical cells (grey matter) are present in inappropriate locations in the brain, due to interruption in their migration to their correct location in the cerebral cortex.

What causes grey matter heterotopia?

Grey matter heterotopias are believed to be due interruption of the normal migration of neurons from the periventricular telencephalic germinal matrix to the cortex and may be due to either genetic abnormalities or infection/trauma. Neuroblasts proliferate in the germinal matrix between 7 and 8 weeks of gestation.

Is grey matter heterotopia a disability?

Psychiatric disorders where grey matter heterotopia has been discovered. The most common neuropsychiatric clinical picture is that of intellectual disability, which ranges from mild to severe in nature, even though many patients with GMH present with normal intellectual functioning.

What is heterotopic tissue?

Heterotopia (Greek origin), literally meaning different location, is the presence of a tissue type normally found in the human body but in an abnormal location [1] and can occur throughout the gastrointestinal tract.

Is grey matter good?

Scoring the brain Grey matter is a diffuse network of brain regions thought to be involved in information processing. It is rich in nerve cell bodies and looks grey to the naked eye. They found that people with high IQ scores had significantly more grey matter in 24 of the regions than people with lower scores.

Can heterotopia cause headaches?

Epilepsy in periventricular nodular heterotopia is common but headache is rare [3]. Asymmetric ventriculomegaly is a common radiological feature and is thought to be a structural consequence of the presence of heterotopia, rather than a disorder of ependymal compliance or CSF dynamics [4].

Does heterotopic ossification go away?

Currently, “there’s no way to prevent it and once it’s formed, there’s no way to reverse it,” says Benjamin Levi, M.D., Director of the Burn/Wound/Regeneration Medicine Laboratory and Center for Basic and Translational Research in Michigan Medicine’s Department of Surgery.

What is ectopic pancreatic tissue?

An ectopic pancreas is defined as pancreatic tissue lacking vascular or anatomic communication with the normal body of the pancreas. It is rarely symptomatic as it is found incidentally at laparotomy most of the time.

Does having more gray matter make one more intelligent?

The scientists went on to show that the twins with a higher density of grey matter, especially in the front part of the brain, were markedly better at doing IQ tests, suggesting that the more grey matter someone had, the more intelligent they should appear to be.

Is gray matter good for brain?

Grey matter contains most of the brain’s neuronal cell bodies. The grey matter includes regions of the brain involved in muscle control, and sensory perception such as seeing and hearing, memory, emotions, speech, decision making, and self-control. These cells are responsible for the movement of muscles.

Does gray matter affect intelligence?

Intelligence linked to size of key brain regions. Size may matter after all, when it comes to IQ. A brain imaging study suggests that human intellect is based on the volume of grey matter in certain brain regions, challenging alternative views about the basis of intelligence.
