Periatrial white matter refers to the region of white matter surrounding the lateral ventricles of the brain, particularly around the atrium where the temporal, occipital, and parietal horns meet. This area is crucial for the connectivity between different brain regions, facilitating communication between the cortex and deeper structures. Changes or damage to the periatrial white matter can be associated with various neurological conditions, including multiple sclerosis and vascular diseases. Its integrity is important for maintaining cognitive and motor functions.

Where is the gray white matter junction in brain?

The gray-white matter junction in the brain is where the gray matter (composed mainly of neuron cell bodies) transitions into white matter (composed mainly of myelinated nerve fibers). This junction is found throughout the brain, reflecting the boundary between the outer cortex and the inner white matter tracts.

Some of brain structures consist of gray or white matter what are they?

The brain's gray matter includes regions like the cerebral cortex, responsible for processing information and generating thoughts. White matter consists of nerve fibers that connect different brain regions, enabling communication between them. Examples of white matter structures include the corpus callosum and internal capsule.
