Pure bilateral ageneses and atrophies. 3. Cerebellar atrophies associated with (a) Disease of the cerebrum.(6) Disease of the spinal cord. 1. Unilateral loss of a lateral (in old sense) lobe may be presentwithout any symptoms according to present developed modes oftesting. Few of these cases have been tested by more recent methods.In certain instances unilateral atrophy has been associated withepileptiform convulsions, or retropulsion, when the superficies of theaffected hemisphere is atrophic; if the atrophy involves a part of thevermis, slight motor signs, such as slowing of the gait, have beenobserved. 2.

Lesion of the lateral part of the left pontinetegmentum, involving the nuclei of the trigeminus, the crossed secondary sensorypaths of the tegmentum, partially involving the superior cerebellar peduncle (Pes)and the median lemniscus (Rm), and not involving the anterior portion of the pons. On the right there is hemianesthesia of the extremities of the syringomyeKc type,above all for pain and temperature sense. On the left there is paralysis of the muscles of mastication (pterygoid, masseter,temporal) by lesion of the motor nucleus of the trigeminus. There is slight anesthesiain the trigeminus legion (sensory nucleus V) and choreo-athetoid movements of theextremities from involvement of the superior cerebellar peduncle. (Dejerine.)
