TWO REPORTS on electroencephalographic studies in cases of lesions of the spinal cord have been published, with different results. Kaplan and Stearns1 reported 15 cases, in all of which the electroencephalograms were abnormal. The abnormalities were not the same, but the paroxysmal nature of the abnormalities was common to all. These paroxysmal discharges were frequently localized over the central sagittal, and precentral areas. In explanation, the authors suggested that the abnormalities might be the result of antidromic volleys in the pyramidal tracts. On the other hand, Merlis and Watson2 reported normal electroencephalographic findings in 16 of the 18 cases of cord injury which they had collected. These injuries had resulted in partial or complete anatomic or functional transection of the cord. In one case the abnormalities were accounted for by associated head injury. Accordingly, the present study was made to investigate the problem further and, if abnormalities were
