Brain spinal cord?
so in spinal cord,myelinated axon ae in white matter. and within brain is in Gray matter?
The brain and spinal cord are continuous and both have white and grey business.
White matter is white becaue of the myelinated nerve fibers. This is the pathway of signals through the nervous system.
Grey thing is where the processing of information is done.
peidi_wu,
Brain functionality requires high interconnectivity and short conduction delays. Thus, the optimal design depends on the number of neurons, interneuronal connectivity, and axon diameter. In selective, the requirement to connect neurons with many fast axons drives the segregation of the brain into white and gray thing. Gray matter contains local networks of neurons that are wired by dendrites and mostly nonmyelinated local axons. White matter contains long-range axons that implement global communication via repeatedly myelinated axons. This not only gives a possible explanation for the structure of various brain regions such as the mammalian neocortex, neostriatum, the avian telencephalon and spinal cord, but also make several testable predictions such as the scaling estimate of the cortical thickness.
I add a association with more detailed information of this subject
