Grey matter in the spinal cord is known as the grey column which travels down the spinal cord distributed in three grey columns that are presented in an "H" shape. The forward-facing column is the anterior grey column , the rear-facing one is the posterior grey column and the interlinking one is the lateral grey column .
The periaqueductal gray (PAG), also known as the central gray, is a brain region that plays a critical role in autonomic function, motivated behavior and behavioural responses to threatening stimuli. [1] [2] PAG is also the primary control center for descending pain modulation. It has enkephalin-producing cells that suppress pain.
What is more, bilateral gray matter changes in the posterior and lateral parietal cortex of medical students memorizing for an intermediate exam could be detected over a period of just three months. These studies of professional training inspired questions about the limits of MR-based morphometry in terms of time periods over which structural ...
The appearance is that of cortical dysplasia, with polymicrogyria more likely than pachygyria due to the small convolutions visible. There are also small foci of grey matter signal in the corpus callosum, deep to the dysplastic cortex (double arrows). These probably represent areas of grey matter heterotopia. Specialty: Neurology

In neuropathology, for example, gray matter heterotopia is the presence of gray matter within the cerebral white matter or ventricles. Heterotopia within the brain is often divided into three groups: subependymal heterotopia, focal cortical heterotopia and band heterotopia.
Graysexual — or “gray-a,” as it’s often referred to — is a normal, valid sexual identity, and it’s important to note that everyone’s definitions on sex and attraction are different.
