[2] Neck or shoulder pain on the ipsilateral side (i.e., the side to which the head is flexed) indicates a positive result for this test.
Von Bogaert, Lhermitte’s colleague, named this type of hallucination “peduncular,” in reference to the cerebral peduncles, as well as to the midbrain and its surroundings. [1] In 1925, Von Bogaert was the first to describe the pathophysiology of peduncular hallucinosis through an autopsy of a patient. [ 5 ]
