M. Laehr. Ueber Störungen der Scbmerz und Temperatur empfindung in Folge von Erkrankungen des Rückenmarkes. — Archiv. f. Psychiatrie, Bd XXVIII, Heft. 3

In a very extensive work, based on the observations of other authors and eleven own cases, Laehr comes to the following conclusions. With syringomyelia, as well as with other central diseases of the spinal cord, the prevalence of disorders of skin sensitivity is of a certain nature. These sensory lesions are similar to those caused by lesions of the posterior roots or transverse cuts of the spinal cord. The anatomical reason for the disorder of skin sensitivity is the destruction of the posterior sacrago substance at the corresponding level of the spinal cord.
