It has recently been reported that focal ischemia induced by occlusion of unilateral middle cerebral artery provoked direct current (DC) potential deflection in the cortical infarct rim. DC potential deflection is suggested to be one of the deteriorating factors for ischemic damage. We aimed to elucidate whether a direct current magnetoencephalography (MEG) can noninvasively record DC potential deflection in focal brain ischemia or not. Fourteen male Wistar rats were used for this study. After anesthesia with pentobarbital, rats were subjected to transcranial occlusion of left middle cerebral artery by electrocauterization.
