Half the brain by >>volume<< being myelinated axons. Myelinated axons are extremely volume-wasteful due to their large width over relatively large distances.
I’m talking about adult brains. Child brains have slightly more axons (less pruning and aging loss has occurred), but much less myelination.

Happy to chat at some point.
