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 white matter consists of tracts that interconnect segments of the spinal cord or connect the spinal cord with the brain. The gray matter appears in a butterfly shape, with ventral and dorsal horns, an intermediate gray matter and, in the thoracic cord, a lateral horn (sympathetic neurons).
