- extrinsic olfactory hallucination
- The term extrinsic olfactory hallucination is indebted to the Latin words extrinsecus (outside), and ol(e)facere (to smell). It was introduced in or shortly before 1971 by the Canadian neurologist William E.M. Pryse-Phillips to denote an "olfactory hallucination (i.e. a hallucination of smell) which the affected individual attributes to an extracorporeal source. The term extrinsic olfactory hallucination is used in opposition to the term "intrinsic olfactory hallucination (i.e. a hallucination which the affected individual believes is emanating from his or her own body, without the intervention of any outside agency).ReferencesPryse-Phillips, W.
