What is GREY white matter interface?
Grey-white differentiation refers to the appearance of the interface between cerebral and cerebellar white matter and grey matter on brain CT and MRI. The term is most often used when trying to differentiate cytotoxic from vasogenic edema.
What does GREY area in brain mean?
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.
What is GREY and white matter of brain?
The white matter refers to those parts of the brain and spinal cord that are responsible for communication between the various gray matter regions and between the gray matter and the rest of the body. In essence, the gray matter is where the processing is done and the white matter is the channels of communication.
What does grey matter on a CT scan mean?
The brain consists of grey and white matter structures which are differentiated on CT by differences in density. Grey matter contains relatively few axons and a higher number of cell bodies.
What causes loss of GREY white matter differentiation?
Diffuse brain swelling and loss of gray matter (GM)–white matter (WM) differentiation is seen on CT for a variety of “primary” fatal conditions, such as trauma [10], cerebral air embolism [11], acute necrotizing encephalopathy [12], fat-embolism [13], and so on.
What’s the difference between GREY and white matter?
What is the difference between grey and white matter in the brain? The grey matter contains the cell bodies, dendrites and the axon terminals, where all synapses are. The white matter is made up of axons, which connect different parts of grey matter to each other.
How are GREY and white matter different?
Is periventricular white matter normal?
Major causes of periventricular white matter (PWM) lesions include normal changes from aging (then they are called UBO’s, for “unidentified bright objects), small strokes, and disorders related to multiple sclerosis (MS). PWM are also correlated with vitamin B6 (pyridoxine) deficiency.
Is there gray matter and white matter in the brain?
As the surface of the brain is filled of many hills and valleys, the inner face between the gray matter and the white matter is irregular as well. The gray matter and white matter interface can be seen below. The gray matter and white matter interface can be seen on this photograph of an autopsied human brain.
What happens to gray matter in the brain after a stroke?
The development of edema within the brain produces subtle parenchymal hypo density changes and mass effect. These initial edematous changes are characterized as a loss of distinction between gray and white matter (blurring of the gray-white interface).
What is the relationship between cortical gray and white matter?
This study investigates the relationship between blurring of the cortical gray and white matter boundary on magnetic resonance imaging (MRI) and global cognitive abilities in FCD.
Is the myelin sheath white or gray matter?
The myelin sheath is white. The primary thinking, perceiving and cognitive functions of the brain happen on in the gray matter of the brain. The neurons in this part of the brain are short enough that the electrical signal would not degrade from the start of the cell body to the axon terminal,…
