A study of the localization of epileptic manifestations is a study of the localization of cerebral function. The movement, the sensation or the disturbance of consciousness observed may seem only a crude caricature of the function normally discharged by the area of brain in question, but from the caricature one may learn to discern the true features of normal cerebral activity.
In this study we have analyzed seventy-five cases of focal epilepsy, after eliminating the cases of generalized epilepsy in which careful study revealed no local sign. In nearly all cases cerebral pneumography was carried out and the patient was operated on under local anesthesia. The seizures which we studied were either spontaneous or induced by hyperpnea, by hydration or by direct cortical stimulation.
This is intended to be a study of human physiology. No effort will be made, therefore, to indicate, except incidentally the reasons for operation, the nature
