gray matter is composed of neuron cells and is concentrated in the cerebral cortex and nuclei and basal ganglia.
white matter is composed ofneuron processes which form tracts connecting parts of the brain with each other and with the spinal cord.
Gray matter consists of nerve cell bodies of the central nervous system. White matter on the other hand is composed of the inter-connecting fibre tracts of the nerves from gray matter.
Die
in the spinal cord which is deeper to the other, the white matter or gray matter? how does this compare to the distrubution in the brain
The corpus callosum is the largest white matter structure in the brain.
The brain is composed of two sides gray matter and white matter. The white matter is the thinking part of the brain while the gray matter is the doing part. The more you are active the more it increases gray matter.
Gray matter and white matter are essentially the same in the brain and spinal cord. The gray matter is the part of the brain and spinal cord that initiate the firing of neurons and the white matter is basically the mode of transportation for the signal.
White matter is found in the inside of the brain and the spinal cord. Grey matter is found in most parts of the brain including the cerebellum and brain stem.
The gray matter consists of neuronal cell bodies where the "action" happens. The white matter of the brain ismyelinated (insulated) axons that transmit messages from one neuron cell body to another, a muscle cell, or a gland.
Gray matter contains most of the neuronal cell bodies in the brain, and involves muscle control and the senses. White matter transfers the messages between different areas of the central nervous system.
Brain tissue is called gray matter because it is gray.
The tissues found in the brain are gray matter and white matter. The gray matter is made up of unmyelinated neurons and it is the area of nerve connections and processing. The white matter is made up of myelinated neurons that connect the regions of gray matter to each other and the rest of the body. The white matter acts as the main information path that speeds up connection between the brain and distant parts of the body.
Franz Josef Gall
To oversimplify it significantly with an analogy, the grey matter is data processing neurons and the white matter is the myelin insulated cabling axons of those neurons that interconnects them to exchange data. Myelin is fatty, giving the white color to the white matter.
