The effects of cold-induced brain edema and white-matter ischemia on the somatosensory evoked response

Leslie N. Sutton, Derek A. Bruce, Frank A. Welsh

Open publisher page 23 citations

Abstract

The electrophysiological effects of cold-lesion edema and white-matter ischemia were studied in cats by reference to the short-latency somatosensory evoked response. The primary cortical waves were found to be considerably delayed following a period of white-matter ischemia; hosever, cold-lesion edema appeared to have no significant effect on the evoked response. The authors conclude that vasogenic edema does not interfere with axonal functioning by an ischemic mechanism.
