The white matter in the cerebral cortex contains cell bodies of neurons

Question

BlackTom AI · Accepted Answer

To analyze the statement, begin by recalling the basic anatomical distinction between gray and white matter in the cerebral cortex.
Option A: True. If we claimed that white matter contains neuron cell bodies, we would be contradicting the core definition of white matter, which is primarily made up of myelinated axons and supporting glial cells rather than neuron soma.
Option B: False. This aligns with neuroanatomy: the cerebral cortex's gray matter houses neuronal cell bodies, dendrites, and synapses, while the white matter lies beneath it and consists chiefly of myelinated axons connecting different cortical and subcortical regions. 
Consider the functional implication: cell bodies are metabolically dense regions that sit in the outer cortex (gray matter) to process information, whereas the long-range wiring that conducts signals between regions is what the white matter primarily provides. 
Option A (True) would misplace the location of neuron soma, implying that the cortical wiring is where neuron cell bodies are concentrated, which would blur the established gray-white matter distinction. 
Option B (False) correctly reflects that white matter does not contain the cell bodies of neurons; instead, it contains axons coated with myelin and glial support, enabling rapid communication between gray matter regions. 
In summary, the statement is incorrect because the white matter does not contain neuron cell bodies; it mainly contains myelinated axons and glial cells, whereas the neuron cell bodies reside in the gray matter of the cortex.
