Brainstem hallucination
   A term suggested in 1991 by the American neurologist C. Miller Fisher (b. 1910) to replace the older term * peduncular hallucination. More specifically, Miller proposes to use the term brain-stem hallucination as an umbrella term for a category comprising the group of peduncular hallucinations and hallucinations attributed to CNS structures in the vicinity of the pedunculus cere-bri. Fisher motivates this proposal as follows. "Although peduncular hallucinations are a well recognized type it might be preferable to include them in a broader category - brain stem hallucinations that would encompass not only peduncular cases proper but also cases in which visual hallucinations are associated with pontine haemorrhage, thalamic haemorrhage, and thalamic infarction."
