As the intracranial pressure was raised by expansion of a supratentorial balloon, the late components of the SER's were suppressed first, followed by the early components of the SER's, then Wave V and Wave IV of the BER's, in that order. This suggests that the nonspecific reticular projections are most vulnerable to compression ischemia, and the specific somatosensory pathways are the next most vulnerable. Neural activity of the auditory pathways in the upper brain stem was also gradually suppressed, but less so than that of the somatosensory pathways. After complete transtentorial herniation, in spite of immediate mass evacuation, the function of the somatosensory pathways was greatly impaired, often irreversibly. The neural activity of the auditory pathways in the upper brain stem revealed progressive recovery during a 3-hour period. The measurements of BER Wave V is thought to be useful in predicting transtentorial herniation.<\/jats:p>","DOI":"10.3171\/jns.1979.51.5.0669","type":"journal-article","created":{"date-parts":[[2009,5,7]],"date-time":"2009-05-07T15:32:34Z","timestamp":1241710354000},"page":"669-676","source":"Crossref","is-referenced-by-count":54,"title":["Acute intracranial hypertension and auditory brain-stem responses"],"prefix":"10.3171","volume":"51","author":[{"given":"Seigo","family":"Nagao","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peter","family":"Roccaforte","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Robert A.","family":"Moody","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1754","reference":[{"key":"b1","series-title":"Anesthesiology","doi-asserted-by":"publisher","first-page":"650","DOI":"10.1097\/00000542-196309000-00013","article-title":"Effects of thiopental on human cerebral evoked responses.","volume":"24","author":"Abrahamian","year":"1963"},{"key":"b2","series-title":"Electroencephalogr Clin Neurophysiol","doi-asserted-by":"publisher","first-page":"331","DOI":"10.1016\/0013-4694(62)90110-4","article-title":"Recovery functions of somatosensory evoked responses in man.","volume":"14","author":"Allison","year":"1962"},{"key":"b3","series-title":"Electroencephalogr Clin Neurophysiol","doi-asserted-by":"publisher","first-page":"461","DOI":"10.1016\/0013-4694(66)90194-5","article-title":"Cerebral somatosensory responses evoked during sleep in the cat.","volume":"21","author":"Allison","year":"1966"},{"key":"b4","series-title":"Stroke","doi-asserted-by":"publisher","first-page":"487","DOI":"10.1161\/01.STR.8.4.487","article-title":"Evoked potential changes during brain retraction in dogs.","volume":"8","author":"Bennett","year":"1977"},{"key":"b5","series-title":"Cortical Evoked Potentials in Man.","first-page":"61","author":"Bergamini","year":"1967"},{"key":"b6","series-title":"Science","doi-asserted-by":"publisher","first-page":"382","DOI":"10.1126\/science.1145206","article-title":"Far-field acoustic response: origins in the cat.","volume":"189","author":"Buchwald","year":"1975"},{"key":"b7","series-title":"Electroencephalogr Clin Neurophysiol","doi-asserted-by":"publisher","first-page":"623","DOI":"10.1016\/0013-4694(72)90099-5","article-title":"The initial positive potential of the human scalp-recorded somatosensory evoked response.","volume":"32","author":"Cracco","year":"1972"},{"key":"b8","series-title":"Am J Physiol","first-page":"718","article-title":"Some afferent diencephalic pathways related to cortical potentials in the cat.","volume":"131","author":"Dempsey","year":"1941"},{"key":"b9","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"145","DOI":"10.3171\/jns.1956.13.2.0145","article-title":"The role of the reticular formation in the coma of head injury.","volume":"13","author":"Foltz","year":"1956"},{"key":"b10","series-title":"J Neurophysiol","doi-asserted-by":"publisher","first-page":"112","DOI":"10.1152\/jn.1939.2.2.112","article-title":"Cortical response to sensory stimulation under deep barbiturate narcosis.","volume":"2","author":"Forbes","year":"1939"},{"key":"b11","series-title":"Ann NY Acad Sci","first-page":"93","article-title":"Somatosensory evoked potentials in healthy subjects and in patients with lesions of the nervous system.","volume":"112","author":"Giblin","year":"1964"},{"key":"b12","series-title":"Electroencephalogr Clin Neurophysiol","doi-asserted-by":"publisher","first-page":"697","DOI":"10.1016\/0013-4694(62)90084-6","article-title":"Distribution of cerebral somato-sensory evoked responses in normal man.","volume":"14","author":"Goff","year":"1962"},{"key":"b13","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"601","DOI":"10.3171\/jns.1973.39.5.0601","article-title":"Vascular pathology of the brain stem due to experimentally increased intracranial pressure: changes noted in the micro- and macrocirculation.","volume":"39","author":"Goodman","year":"1973"},{"key":"b14","series-title":"Surg Forum","first-page":"484","article-title":"Clinical applications and results of evoked potential data in patients with severe head injury.","volume":"26","author":"Greenberg","year":"1975"},{"key":"b15","series-title":"J Neurosurg","doi-asserted-by":"publisher","first-page":"163","DOI":"10.3171\/jns.1977.47.2.0163","article-title":"Evaluation of brain function in severe human head trauma with multimodality evoked potentials.
