The eponym Bthe triangle of Guillain-Mollaret^ (GMT), also known as the dentato-rubro-olivary (DRO) pathway or myoclonic triangle (Fig. 1 and cover), remembers two physicians who contributed to defining this polygon in 1931 [1]. French neurologist Georges Charles Guillain (Fig. 1) was born in 1876 in Rouen and began to study medicine in his native town after customary schooling. He received his clinical education at several hospitals in Paris, completed his first scientific study on traumatic lesions of the plexus brachialis, and was awarded his medical doctorate. He worked on nervous diseases during the First World War and in 1923 he gained the professorship of neurology at the Hôpital de la Salpêtrière in Paris. In 1920, Guillain, together with Barré, reported their famous clinical experience defining what is now known as Guillain-Barré syndrome. In 1931, Guillain and Mollaret described the famous anatomical connections encompassing the contralateral dentate nucleus (DN), ipsilateral red nucleus (RN), and ipsilateral inferior olivary nucleus (ION), called the GMT [1]. He was a member of many international medical societies including American and Japanese and he received many scientific honors [5]. In 1947, he retired and, in 1961, died in Paris. French physician Pierre Mollaret (Fig. 1) was born in 1898 in Auxerre. Together with his teacher Georges Charles Guillain, Mollaret worked for many years on diseases of the nervous system. He received his academic degree in 1926 and completed his thesis for the medical doctorate in 1929; then he worked at the Hôpital de la Salpêtrière. Mollaret was head of the laboratory at the Pasteur Institute from 1935 to 1941 and he worked in the malaria department of the military hospital in Casablanca during the Second World War. Importantly, in 1944, he was the first to report several patients with recurrent aseptic meningitis, known also as Mollaret meningitis [2]. Mollaret made many scientific contributions to neurology
