To exercise mesmerism on; to spellbind; to enthrall. 1913, Joseph C. Lincoln, chapter 4, in Mr. Pratt's Patients: Then he commenced to talk, really talk. and inside of two flaps of a herring's fin he had me mesmerized, like Eben Holt's boy at the town hall show. He talked about the ills of humanity, and the glories of health and Nature and service and land knows what all.
White matter develops and changes across our life span in a pattern strikingly different from gray matter. We do not complete the formation of brain myelin until many years after birth, perhaps past 20 years of age; by contrast, we have our full complement of brain neurons at birth.
The part of your brain where the nerve cell bodies themselves are is the grey matter.. Think of your brain as a bunch of networked computers, with the computers as the cell bodies and the wires connecting them as the axons, and that's a decent enough analogy. Different processes can cause changes in the white matter.
