White matter
no the report says normal gray white differentiation
Myelination
the thalamic nuclei is made of unmyelinated axons which are gray matter
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.
Gray matter is deep to white matter in the spinal cord. Gray matter contains cell bodies of neurons and is responsible for processing sensory information and initiating motor responses, while white matter contains nerve fibers that transmit signals between different parts of the nervous system.
Gray Matter
gray
A horn is the gray matter of the spinal cord, and a column consist of white matter.
That would be gray matter.

no the report says normal gray white differentiation
The white matter is located on the outside of the gray matter in the spinal cord.
The brainstem contains both white and gray matter. White matter is found on the inside, made up of myelinated nerve fibers, while gray matter is located on the outside and consists of nerve cell bodies.
It is superficial to the white matter.

Myelination
Gray matter doesn't fit. White matter is white because it has myelin covering the axons. And the myelin fiber tract is "white" for the same reason.
