AUDIOVISUOALGESIC HALLUCINATION

   Also known as audiovisuoalgesic synaesthesia. Both terms are indebted to the Latin words audire (to hear) and visio (sight) and to the Greek noun algos (pain). They were introduced in or shortly before 1979 by the American neurologists Daniel Enrique Jacome and Robert Jerome Gumnit to denote a " compound hallucination comprising an auditory component, a visual component, and a pain component. The subject described in Jacome and Gumnit's paper experienced audiovisuoal-gesic hallucinations in the context of "aurae preceding epileptic seizures, characterized by a sudden onset of pain in the region of the right trigem-inal nerve, the simultaneous auditory perception of the word "Five" in both ears, and the visual perception of the number 5 against a grey background before both eyes.
