title: [Electroencephalographic curves in diseases of the basomedian cerebral structures].
abstract: In twenty-two patients bilaterosymmetric, slow frequencies occurring in groups frontoprecentrally and frontoparietally, respectively, were found for a total of thirty-four spaceoccupying processes of basomedian structures. Such alterations should not be considered to be characteristic of tumors located adjacent to the median line, but may be regarded as an important indication. The changes themselves are due to the diffuse thalamocortical system as well as the reticular activating system. The overlapping of functions of these systems and the different responses of equal structures to different intensities of stimulation make it impossible for clinicians to assign them to individual basomedian structural levels even if necropsy records and reports on surgical operations are taken into consideration.
