Ganglion

The OED (228) assures us that a ganglion is a tumor, or a knot on a nerve forming a center from which nerve fibers radiate, or a class of organs that includes the thymus gland, the thyroid body, and the adrenals. The Random House Dictionary (250) uses similar terms but adds “a center of intellectual or industrial force, activity, etc.” I have heard the word used as meaning a snarl. Several of my knowledgeable friends (265, 273, 289, 326) opine that Ralph’s nervous system was immobilized by conflicting signals into a quivering pulp. Prestige (243) on the other hand believes that Ralph was carried away and simply used an impressive-sounding word in the wrong place. Occam and I tend to support Prestige.
