TY - JOUR PY - 1977// TI - Evaluation of brain function in severe human head trauma with multimodality evoked potentials. Part 1: Evoked brain-injury potentials, methods, and analysis JO - Journal of neurosurgery A1 - Greenberg, R. P. A1 - Mayer, D. J. A1 - Becker, D. P. A1 - Miller, J. D. SP - 150 EP - 162 VL - 47 IS - 2 N2 - Methods for obtaining multimodality evoked potentials, somatosensory, visual, auditory, and auditory brain-stem potentials in patients with severe head trauma are described. A method of analyzing abnormal multimodality evoked potentials (graded evoked brain-injury potentials) is proposed that defines the degree of abnormality of the electrophysiological data and expresses it simply in four grades per modality. Data from 20 normal subjects are given for comparison with the abnormal data obtained from 51 patients with head trauma.
