Moritz Schiff, Charles Sherrington, border cells, frogs, cats and a zebra with abnormal clinical signs.

This observation in mammals was repeated by Sherrington 40 years later, and the eponym "Schiff-Sherrington reflex" was thus coined (Feinsod, [10]; Ruch & Watts, [27]; Wang, [36]). The case report presented by Frers et al. ([12]) describes an interesting neurological syndrome observed in a zebra, likely to be consistent with the Schiff-Sherrington syndrome (SSS). Interested in those descriptions, Ruch and Watts ([27]) confirmed the Sherrington findings after interrupting conduction in the spinal cord and were the first authors to suggest: "... cephalad release of function should probably be designated the Schiff-Sherrington phenomenon" because Schiff described this syndrome in amphibian spinal cord 40 years before Sherrington. Sir Charles Sherrington first studied this network (Sherrington & Laslett, [32], [33]), currently named the propriospinal system (neurons that are intrinsic to the spinal cord and whose axons terminate within its boundaries) (Conta & Stelzner, [6]).
