✓ Cortical removals which included precentral and postcentral facial representations resulted in relief of facial pain in two patients. Because of known failures following only postcentral (SmI) ablations, these operations were designed to eliminate also the cutaneous afferent projection to the precentral gyrus (MsI) and the second somatic sensory area (SmII). In one case burning pain developed after a stroke involving the brain stem and was not improved by total fifth nerve section; prompt relief followed corticectomy and lasted until death from heart disease 20 months later. In the other case persistent steady pain that developed after fifth rhizotomy for trigeminal neuralgia proved refractory to frontal lobotomy; relief after corticectomy was immediate and has lasted 14 months. Cortical localization was established by stimulation under local anesthesia. Each removal extended up to the border of the arm representation and down to the upper border of the insula. Such a resection necessarily included SmII, and in one case responses presumably from SmII were obtained before removal. The suggestions of Biemond (1956) and Poggio and Mountcastle (1960) that SmII might be concerned with pain sensibility may be pertinent in these cases.

The activities of 20 enzymes in normal, heterozygous, and dystrophic mouse muscle were studied by means of quantitative microchemical methods. Enzyme activities in normal and heterozygous muscle were essentially the same. In dystrophic muscle glucose-6-P dehydrogenase, 6-P-gluconic dehydrogenase, glutathione reductase, peptidase, ß-glucuronidase, and glucokinase activities were significantly higher than in normal muscle, while α-glycero-P dehydrogenase and lactic dehydrogenase activities were significantly lower. The pattern of enzyme activities found in normal gastrocnemius denervated by nerve section was strikingly similar to that in dystrophic muscle.
