SENSORIAL HALLUCINATION

Also known aspsychic hallucination. The term sensorial hallucination is indebted to the Latin nounsensorium, which means seat of the senses, or brain. It was used in 1846 by the French dream researcher Maurice Macario to denote a hallucination which the affected individual takes to be an ordinary sense perception, even though it is mediated by chemical changes or "nerve fibre vibrations" in the brain. Macario's concept ofthe sensorial hallucination would seem to fit in with the * centrifugal theory of hallucinatory activity. The term was used by him in opposition to the terms * ganglionic hallucination, * intuitive hallucination, and * sthenic hallucination.
