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 signal changes on the MRI essentially means that on the MRI, the white matter showed some scattered bright spots. White matter in the brain refers to the fiber tracts that carry information to and fro from the brain. My first question when somebody asks me what next and what does this mean is to ask them why was the MRI done in the first place.
