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.
White matter is composed of electrically insulating material that is found commonly in the deeper parts of the brain and in the superficial areas of the spinal cord. It is named white matter primarily because its color is white. The reason behind its color is that white matter is composed myelin and veined capillaries. Seventy to eighty-five percent of myelin is mostly composed of lipids while the remaining fifty to thirty percent are proteins. It is because of its lipid component that gives off a white color when exposed.
