The pyramidal fibers becomecovered with myelin only during the first few months after normal birth. n8 INFLAMMATION OF THE BRAIN According to Van Gehuchten, at seven months the pyramidal fibers areabsent in the spinal cord and can be traced only in the brain and stands to reason that there is no continuity between the cortex, whichsends out stimulation, and the peripheral nerves, or else the stimulationsent out from the cortex to the spinal centers is not properly transmittedfor want of normal pyramidal fibers. The rigidity of the muscles indiplegia can therefore be explained either by increase of the muscular. Fig. 68.—Diplegia, LittlesDisease.

Fournier had long ago called attention to hereditary syphilis as an etio-logical factor in Littles disease. In a large number of cases the diseaseis present in individuals whose parents were distinctly syphilitic. Notinfrequently diplegic children present certain stigmata of syphilis, suchas hydrocephalus, internal strabismus, etc. In some cases at autopsy INFLAMMATION OF THE BRAIN 119 of diplegics lesions of syphilitic nature had been found: sclerotic andgummatous formations, meningeal conditions, cerebral endarteritis,meningo-myelitis. Finally, Wasserman reaction has been frequentlyfound positive in diplegics. On the other hand, a negative Wassermandoes not exclude syphilis. The fact that diplegia is observed frequentl
