Neurology, 2000
Gray matter heterotopia are common malformations of cortical development. From a clinical perspective, affected patients are best divided into three groups: subependymal, subcortical, and band heterotopia (also called double cortex). Symptomatic women with subependymal heterotopia typically present with partial epilepsy during the second decade of life;

Radiology, 1970
Heterotopic nodules of gray matter beneath the ependymal surfaces of the lateral ventricles of the brain present a characteristic appearance at pneumography. Such nodules usually occur in association with other cortical anomalies; severe psychomotor retardation is associated.

Science of Aging Knowledge Environment, 2005
Like antique soda dispensers that stand empty because factories that make glass bottles have crumbled, old hairs lose color because cells that manufacture the locks' pigment source vanish, new research shows. The results indicate that stem cells for pigment-makers die off, which causes hair to go gray.

Gray matter volume differences and the effects of smoking on gray matter in schizophrenia
Schizophrenia Research, 2007Many studies have evaluated differences in gray matter volume in schizophrenia, but have not considered the possible effects of smoking, which is extraordinarily common in people with the illness. The present study used voxel-based morphometry (VBM) to examine differences in gray matter in subjects with schizophrenia and evaluate the effects of smoking

Gray matter alterations in parosmia
Neuroscience, 2011Parosmia is a common olfactory disorder. In this condition, odors are perceived in a different quality than usual. This distorted olfactory percept is typically reported to be unpleasant. Little is known about the pathophysiology of this phenomenon. Previous studies demonstrated smaller volumes of the olfactory bulbs in patients with parosmia compared ...

Gray matter heterotopias in schizophrenia
Schizophrenia Research, 1993Gray matter heterotopias (GMHs) are a type of neuronal migration anomaly in which collections of normal neurons are abnormally located secondary to an arrest of radial migration. They are often manifested clinically by seizures and cognitive, motor, and language deficits.

Abstract Spinal cord gray matter is a complex tissue with the following components: ( l) neurons with a long axon, (2) neurons with a short axon, (3) freely ending ramifications of collaterals arising in the white matter, (4) freely ending terminal arborizations of parent fibers in the white matter, (5) local collaterals (from spinal ...

The spinal gray matter is a complex structure with the following components: 1st., numerous nerve cells of long axon; 2nd., very few cells of short axon; 3rd., free ramifications of collaterals from white matter; 4th., free terminal arborizations of white matter fibers; 5th., initial collaterals, i.e.
