"1852 zeigen der deutsche Physiologe Julius Ludwig Budge 1811-1888 und der englische Neurophysiologe Augustus Volney Waller 1816-1870 dass die für die Pupille bestimmten Fasern des Sympathikus ihren Ursprung im Rückenmark haben. Wenn man die vorderen Wurzeln der Nervenpaare durchschneidet die aus dem Centrum ciliospinale hervortreten - also aus der Wurzel der zwei oder drei ersten dorsalen Spinalnervenpaare - so sieht man an der Pupille sogleich die für die durchtrennung des Halssympathikusstrangs charakteristische Verengung."

Schweiz Med Forum 2014;1434: pp.605-607 "In 1851 Waller abandoned his practice to devote himself entirely to research and moved to Bonn Germany. During his 5 years in Bonn Waller turned to his second major focus in neurophysiology the autonomic nervous system. In collaboration with Julius Ludwig Budge Waller studied the pupillary action and nerve supply to the iris. Their important observations were reported in 1851 and 1852 in the Comptes Rendus published by the French Academy of Sciences. With carefully executed experiments Budge and Waller showed the influence of the cervical portion of the sympathetic nerve in dilatation of the pupil. Using the Wallerian method to trace the dilator fibers they followed the fibers in the sectioned sympathetic trunk to the first and second thoracic segments of the cord. If this region was stimulated in an intact animal there was pupillary dilatation; if the cervical sympathetic nerve was sectioned pupillary dilatation was abolished. Budge and Waller named the area controlling the dilatation of the pupils the ''ciliospinal center.'' Their work on the ciliospinal center won Budge and Waller the 1852 Monthyon Prize awarded by the French Academy of Sciences. They went on to demonstrate the action of the cervical sympathetic nerves on vasoconstriction." Venita Jay: Augustus Volney Waller. Arch Pathol Lab Med 126/9 2002: pp: 1018-1019. unknown
